Electrons carry _______ charge. positive zero negative variable
Electrons carry a negative charge. Electrons revolve in shells around the nucleus of the atom. The nucleus contains protons and neutrons. Protons are positively charged sub-atomic particles and neutrons are neutrally charged. The number of electrons in an atom largely decides the properties of the atom. The radius of the electron is 2.82 x 10-15 m. It has a radius 2.5 times larger than a proton. The charge of the electron is -1.602 x 10-19 Coulomb.
