1 Electrons-Subatomic particle that has almost no weight and carries a negative charge; orbits in a shell about the nucleus of an atom. 2  Neutrons-Subatomic particle that has a weight of one atomic mass unit, carries no charge, and is found in the nucleus of an atom.
In an atom of matter, an electrical charge occurs whenever the number of protons in the nucleus differs from the number of electrons surrounding that nucleus. If there are more electrons than protons, the atom has a negative charge. If there are fewer electrons than protons, the atom has a positive charge. The amount of charge carried by an atom is always a multiple of the elementary charge, that is, the charge carried by a single electron or a single proton.
