An elementary negatively charged particle orbiting within an atom, the electrons are arranged in shells - and it is the outermost shell electrons which take part in bond formation.
Particle in an atom carrying a negative charge.
An elementary particle with a unit electrical charge and a mass 1/1837 of the proton. Electrons surround the atom's positively charged nucleus and determine the atom's chemical properties. In our diagrams, an electron is represented by this: Found on https://www.encyclo.co.uk/local/20039
A tiny speck of electric charge, so-far impossible to break into smaller pieces, weighing in at 9.109 Ã— 10-31 kg and a charge of 1.602 Ã— 10-19 Coulombs. An electron is so small that its 'size' is a nebulous concept; if it were a little round ball, it would be about 10-15 m across. Found on http://www.encyclo.co.uk/local/20046

The electron is a low mass particle ( 1/1836 that of a Photon ) 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 . The electrons is closely related (identical in fact) to the Beta Particle .
