An electron is a negatively charged subatomic particle that

occupies the orbitals around atomic nuclei, allows atoms to

participate in chemical reactions, is the charge carrier in metals

for electrical current, and transports thermal energy in

metals.

The word electron comes from the Greek word elektron, the word

for amber (fossilized tree sap) that when rubbed on wool produces

static electricity.
