Answer

Brief Explanations:

Electrons are negatively - charged subatomic particles with a charge of - 1. They have a very small mass, virtually zero compared to protons and neutrons. They are located outside the nucleus in electron shells. The arrangement of electrons in these shells determines the chemical reactivity of an atom. The identity of an atom is determined by the number of protons in the nucleus, not electrons.

Answer:

charge: -1 mass: virtually zero location: outside the nucleus role in an atom: responsible for reactivity
