The electron is a low mass particle ( 1/1836 that of a proton ) with a unit negative electric charge. in simple terms the electrons are said to orbit around the nucleus of atoms . positively charged electrons can also exist, these being known as positrons
Negatively charged particle of an atom.
An elementary particle of an atom with a negative electrical charge and a mass of 1/1837 of a proton; electrons surround the positively charged nucleus of an atom and determine the chemical properties of an atom. the movement of electrons in an electrical conductor constitutes an electric current.
An elementary particle of an atom with a negative electrical charge and a mass of
One of the fundamental constituents of atoms. the electron is a very small negatively charged particle with a rest mass of approximately 1/1836 that of the hydrogen atom, or 9.107 x 10-28 gm. it has an electric charge of 4.802 x 10-10 statcoulomb (the electrostatic unit of charge). electrons appear to be uniform in mass and charge.
