an electron

تعريف an electron في الإنجليزية الإنجليزية القاموس.: corpuscle
electron: An alloy of magnesium and aluminum
electron: The subatomic particle having a negative charge and orbiting the nucleus; the flow of electrons in a conductor constitutes electricity
electron: {n} a name given to the sun, the supposed center and source of electricity
electron: e
electron: A negatively charged sustainable elementary particle that consists of ordinary matter Atoms consist of a positively charged nucleus surrounded by a cloud of negatively charged electrons Electrons emitted from the nucleus of an atom are called beta particles
electron: Electrons are small nuclear particles with a negative electrical charge usually found moving around atomic nuclei When not associated with atomic nuclei, they are often referred to as beta particles They have a mass of 9 10 X 10-28 grams; this is 1/1836 the mass of a proton
electron: The subatomic particle that possesses the smallest possible negative electric charge (4 80298 * 10-10 electrostatic units) See physical constants, table
electron: A negatively charged particle; one of the three basic kinds of particles that make up an atom Electrons can either be free or orbit the nucleus of an atom
electron: The smallest particle of negative electricity
electron: 1 A subatomic particle with a negative electric charge that orbits the nucleus of an atom 2 The basic particle that makes up an electric current
electron: A small, indivisible particle that orbits the nucleus of an atom
electron: It has been detected only when in rapid motion; its mass, which is electromagnetic, is practically constant at the lesser speeds, but increases as the velocity approaches that of light
electron: an elementary particle with negative charge
electron: 4 x 10-10 electrostatic units
electron: An atom from which an electron has been detached has a positive charge and is called a coelectron
electron: An elementary particle with a unit electrical charge and a mass 1/1837 that of the proton Electrons surround the atom's positively charged nucleus and determine the atom's chemical properties
electron: The negatively charged component of an atom and the unit of negative electrical charge that makes up a current search
electron: a fundamental particle of very low mass, carrying a negative electric charge and found in all atoms Electrons can be energized or even torn from atoms by light and by collisions, and they are responsible for many electric phenomena in solid matter and in plasmas
electron: The least massive electrically charged particle, therefore absolutely stable It is the most common lepton with charge -1 An electron is one of the fundamental particles in nature Fundamental means that, as far as we know, an electron cannot be broken down into smaller particles Electrons are responsible for many of the phenomena that we observe in everyday life Mutual repulsion between electrons in the atoms of the floor and those within your shoes keeps you from sinking and disappearing into the floor!!! Electrons carry electrical current and successful manipulation of electrons allows electronic devices, such as the one you are using, to function
electron: negatively-charged subatomic particle that moves around the atomic nucleus in specific energy levels It has about 1800 times less mass than the proton and neutron
electron: Subatomic particle (with wave-like qualities!), negatively charged Found in all atoms; balances charge of nucleus
electron: A negatively charged particle commonly found in the outer layers of atoms The electron has only 0 0005 the mass of the proton
electron: A minute atomic particle possessing the smallest amount of negative charge found in nature In an atom the electrons rotate around a small nucleus The weight of an electron is so incredibly small that it would take 500 octillions ( followed by 27 zeros) of them to make a pound It is only about a two-thousandth of the mass of a proton or neutron See also: Proton, Neutron
electron: A negatively charged elementary particle that normally resides outside (but is bound to) the nucleus of an atom
electron: An electron is a tiny particle of matter that is smaller than an atom and has a negative electrical charge. a very small piece of matter with a negative electrical charge that moves around the nucleus (=central part) of an atom proton, neutron neutron (electro- + -on (as in ion)). Lightest electrically charged subatomic particle known. It carries a negative charge (see electric charge), the basic charge of electricity. An electron has a small mass, less than 0.1% the mass of an atom. Under normal circumstances, electrons move about the nucleus of an atom in orbitals that form an electron cloud bound in varying strengths to the positively charged nucleus. Electrons closer to the nucleus are held more tightly. The first subatomic particle discovered, the electron was identified in 1897 by J. J. Thomson. electron microscopy electron spin resonance electron paramagnetic resonance EPR
electron: Amber; also, the alloy of gold and silver, called electrum
electron: a subatomic particle possessing negative charge
electron: the sub-atomic particle, with a negative charge, that orbits the nucleus of an atom
electron: One of those particles, having about one thousandth the mass of a hydrogen atom, which are projected from the cathode of a vacuum tube as the cathode rays and from radioactive substances as the beta rays; called also corpuscle
electron: {i} negatively charged particle which is a fundamental component of matter and exists independently or outside the nucleus of an atom (Physics, Chemistry)
electron: A negatively charged particle that is a constituent of an atom
electron: Electrons are all of one kind, so far as known, and probably are the ultimate constituents of all atoms
electron: A light atomic particle with a fixed negative electric charge
electron: (chem) A subatomic particle with a negative electric charge equal in magnitude to the positive charge of the PROTON but with a much smaller MASS; electrons orbit the ATOM's positively charged nucleus and determine its chemical properties
electron: The electron carries (or is) a natural unit of negative electricity, equal to 3
electron: A sub-particle of an atom that contains a negative atomic charge
electron: An sub-atomic particle which allows the atom to react with its environment and form bonds with other atoms Electrons and their orbits around the nucleus of an atom account for most of the physical properties of the element Used extensively in Electron Microscopy
electron: A subatomic (elementary) particle carrying a unit negative charge
electron: A negatively charged particle that orbits rapidly around the nucleus of an atom See also proton
