What is an electron?


An electron is the negative particle of an atom that is found in the atom's shells that surround the nucleus. The mass of an electron is extremely small compared to that of the atom's protons and neutrons. Electrons permit the atom to participate in chemical bonds.

An atom is composed of electrons, protons and neutrons. The protons are the particles in the atom that have a positive charge, while neutrons have a neutral charge. Protons and neutrons are found in the nucleus of an atom. The nucleus has a positive charge due to the presence of the protons; this positive charge allows it to adhere to the negative electrons to create the atom.
