Definition von isotopes im Englisch Englisch wörterbuch: One of two or more atoms with the same atomic number (the same chemical element) but with different atomic weights An equivalent statement is that the nuclei of isotopes have the same number of protons but different numbers of neutrons Isotopes usually have the very nearly the same chemical properties, but somewhat different physical properties (DOE TRADE Glossary and Acronyms of Emergency Management Terms ORAU 91/K-37 November 1991 ) Back to Top; Atoms with the same atomic number, but different mass numbers; atoms having different atomic masses or mass numbers but the same atomic number; Nuclides with the same number of protons, such as 12C, 13C, and 14C; One of two or more atoms having the same atomic number but differing in atomic weight and mass number; Atoms of the same element that have equal numbers of protons, but different numbers of neutrons Isotopes of an element have the same atomic number by different atomic mass For example, uranium-238 and uranium-235; plural of isotope; Two atoms of the same element but having different numbers of neutrons in the nucleus are called isotopes; Forms of the same element having identical chemical properties but differing in their atomic masses (due to different numbers of neutrons in their respective nuclei) and in their nuclear properties (e g , radioactivity, fission, etc ) For example, hydrogen has three isotopes, with masses of 1 (hydrogen), 2 (deuterium), and 3 (tritium) units, respectively The first two of these are stable (nonradioactive), but the third (tritium) is a radioactive isotope Both of the common isotopes of uranium, with masses of 235 and 238 units, respectively, are radioactive, emitting alpha particles, but their half-lives are different Furthermore, uranium-235 is fissionable by neutrons of all energies, but uranium-238 will undergo fission only with neutrons of high energy See Nucleus; Elements with the same number of protons but have different numbers of neutrons, and thus different masses Back to top K; Atoms of the same element which have the same number of protons but a different number of neutrons in the nuclei Top; Two or more nuclides having an identical nuclear charge (i e same atomic number) but differing atomic mass Such substances have almost identical chemical properties but differing physical properties, and each is said to be an isotope of the element of a given atomic number The difference in mass is accounted for by the differing number of neutrons in the nucleus; atoms with the same atomic number and different numbers of neutrons; Atoms of the same element that have equal numbers of protons, but different numbers of neutrons Isotopes of an element have the same atomic number but different atomic mass For example, uranium-238 and uranium-235; atoms with the same number of protons, but different numbers of neutrons; forms of the same element whose nuclei have the same number of protons, but different numbers of neutrons ex , uranium-234, uranium-235, and uranium-238; atoms of the same element (the same number of protons) with different numbers of neutrons They have identical atomic numbers but different mass numbers; Nuclei containing the same number of protons but different numbers of neutrons Most elements can exist in several isotopic forms A common example of an isotope is deuterium, which differs from normal hydrogen by the presence of an extra neutron in the nucleus; Atoms of the same element having the same chemical properties but differing in mass and in the physical properties that depend on their mass; forms of the same chemical element that differ only by the number of neutrons in their nucleus Most elements have more than one naturally occurring isotope Many isotopes have been produced in reactors and scientific laboratories (BEMR, June 1996, pg GL-5); Different forms of the same chemical element that differ only by the number of neutrons in their nucleus Most elements have more than one naturally occurring isotope Many more isotopes have been produced in reactors and scientific l aboratories; All elements have isotopes, some more than others There are two kinds of isotope, stable and unstable A stable isotope does not disintegrate and is therefore not radioactive An unstable isotope is radioactive and disintegrates to form other elements; Atoms whose nuclei contain the same number of protons but different numbers of neutrons; Forms of a single element that differ in atomic mass due to a different number of neutrons in the nucleus; Atoms having different atomic masses or mass numbers, but the same atomic number; Two or more forms of atoms of the same element with different masses; atoms containing the same number of protons but different numbers of neutrons
isotope: To define or demonstrate an isotopy of (one map with another)
isotope: Any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei. As a consequence, atoms for the same isotope will have the same atomic number but a different mass number (atomic weight)
medical isotopes: plural form of medical isotope
isotope: An isotope of an element has the same number of protons, but a different number of neutrons as a normal atom Because isotopes contain more neutrons, they are heavier than normal atoms, causing them to behave slightly differently This is why isotope ratios are important to study
isotope: Atoms of the same element that have the same number of protons (and hence the same chemical properties), but a different number of neutrons, and therefore, different atomic weights
isotope: Atoms that have the same number of protons but a different number of neutrons They are atoms of the same element that have different masses The isotope number is the number of protons plus the number of neutrons More about isotopes
isotope: One of a group of nuclides that have the same number of protons in their nuclei and a different number of neutrons Many elements have isotopes that are unstable, undergo radioactive decay and emit ionizing radiation as they decay or transform into other elements or isotopes
isotope: Form of an element where the number of neutrons in its atomic nucleus is different than the number of protons
isotope: One of multiple forms of an element that has a different number of neutrons than other atoms of that element Some elements have isotopes that are unstable or radioactive, while others have "stable isotopes " Stable isotopes are not radioactive, and do not decay over time For example, most nitrogen atoms have 14 neutrons, while a very small percentage of naturally-occurring nitrogen atoms have 15 neutrons These 15N atoms are referred to as stable isotopes It is possible to use special equipment to determine how much of a stable isotope is present in something For example, scientists can take a leaf sample and determine how much of the nitrogen present in the leaf has 14 neutrons and how much has 15 neutrons Because stable isotopes do not break down, and because scientists can measure exact quantities present in samples, it is possible to use stable isotopes as tracers
isotope: Any of two or more atoms of an element having the same number of protons, but a different number of neutrons in its nucleus. As a consequence, it will have the same atomic number but a different mass number (atomic weight)
isotope: A species of nucleus with a fixed number of protons and neutrons The term isotope is usually used to distinguish nuclear species of the same chemical element (i e , those having the same number of protons, but different numbers of neutrons), such as iodine 127 and iodine 131
isotope: Chemically identical but anatomically different forms of an element (the number of neutrons are different so the atomic weight differs)
isotope: nuclei of the same element that have the same atomic number but different atomic mass and neutrons
isotope: An atom having the same number of protons in its nucleus as other varieties of the element but has a different number of neutrons
isotope: Two atoms are isotopes if they have the same number of protons and electrons, but a different number of neutrons
isotope: One of two or more atoms having the same number of protons in its nucleus, but a different number of neutrons and, therefore, a different mass
isotope: One of two or more forms of a single element; the atoms of each isotope have the same number of protons but different numbers of neutrons in their nuclei Thus isotopes have the same atomic number but differ in atomic mass
isotope: One of two or more variations of the same chemical element, differing in the number of neutrons not the number of protons
isotope: Atoms having the same number of protons but a different number of neutrons Two isotopes of the same atom are chemically similar to each other, and therefore difficult to separate, but may have different nuclear properties Isotopes are designated by their atomic mass numbers (total number of protons and neutrons) Uranium 235 and uranium 238 are isotopes
isotope: One of two or more forms of an element having the same atomic number but different atomic weights
isotope: {i} form of a chemical element which has the same atomic number as the other forms but a different atomic weight (Chemistry)
isotope: one of two or more atoms with the same atomic number but with different numbers of neutrons
isotope: Isotopes are atoms that have the same number of protons and electrons but different numbers of neutrons and therefore have different physical properties. tritium, a radioactive isotope of hydrogen. one of the possible different forms of an atom of a particular element (=simple chemical substance) (iso- + topos ). One of two or more species of atoms of a chemical element having nuclei with the same number of protons but different numbers of neutrons. They have the same atomic number and hence nearly identical chemical behaviour but different atomic masses. Most elements found in nature are mixtures of several isotopes; tin, for example, has 10 isotopes. In most cases, only stable isotopes of elements are found in nature. The radioactive forms break down spontaneously into different elements (see radioactivity). Isotopes of all elements heavier than bismuth are radioactive; some occur naturally because they have long half-lives
isotope: Two nuclei of the same element which have the same atomic number but different masses They contain the same number of protons but a different number of neutrons Uranium-238 contains 92 protons and 146 neutrons while the isotope U-235 contains 92 protons and 143 neutrons Thus the atomic weight (atomic mass) of U-238 is three higher than of U-235
isotope: Different forms of atoms of the same element They have the same number of protons in their nuclei but a different number of neutrons (the same atomic number but different atomic weights) Uranium-238 and uranium-235 are isotopes of uranium Isotopes may be stable (not spontaneously decaying) or unstable (spontaneously decaying, emitting ionizing radiation)
isotope: one of two or more species of atoms of the same chemical element that have the same atomic number and occupy the same position in the periodic table They are nearly identical in chemical behavior, but they differ in atomic mass or mass number Therefore, they behave differently in the mass spectrograph, in radioactive transformations, and in physical properties, and may be separated or detected by means of these differences
isotope: An atomic form of an element having a particular number of neutrons Different isotopes of an element have the same number of protons but different numbers of neutrons and hence different atomic mass, eg U-235, U-238 Some isotopes are unstable and decay (qv) to form isotopes of other elements J-O
isotope: One of two or more forms of an element that have the same number of protons (atomic number) but differing numbers of neutrons (mass numbers) Radioactive isotopes are commonly used to make DNA probes and metabolic tracers
isotope: Atoms of the same element that have an equal number of protons (and hence the same chemical properties) but a different number of neutrons and, therefore, different atomic weights Although chemical properties are the same, radioactive and nuclear (radioactive decay) properties may be quite different for each isotope of an element
isotope: One of several forms of an element, distinguished by different number of neutrons
isotope: a sub-group of an element in which the atomic nucleus has the same number of neutrons, as well as, the same number of protons All of the atoms of an element will have very nearly the same chemical properties, but the isotopes can have very different nuclear properties
