Question

question 19 4 pts what is true about an electron? charge choose mass choose outside the nucleus virtually zero determines the identity of the atom -1 heavy responsible for reactivity location role in an atom choose

Explanation:

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
