(Biyokimya) isotope

To define or demonstrate an isotopy of (one map with another)

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

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

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

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

Form of an element where the number of neutrons in its atomic nucleus is different than the number of protons

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

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)

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

Chemically identical but anatomically different forms of an element (the number of neutrons are different so the atomic weight differs)

nuclei of the same element that have the same atomic number but different atomic mass and neutrons

An atom having the same number of protons in its nucleus as other varieties of the element but has a different number of neutrons

Two atoms are isotopes if they have the same number of protons and electrons, but a different number of neutrons

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

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

One of two or more variations of the same chemical element, differing in the number of neutrons not the number of protons

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

One of two or more forms of an element having the same atomic number but different atomic weights

{i} form of a chemical element which has the same atomic number as the other forms but a different atomic weight (Chemistry)

one of two or more atoms with the same atomic number but with different numbers of neutrons
