Question

Name the three fundamental subatomic particle. Give their mass and charge.​

Answer 1

Answer:

Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged.

Answer 2

Magnitude of elementary charge |e| = 1.6x10^-19 Coulumb

Neutron

0 Coulumb

1.67x10^-27 kilogram

Electron

-e Coulumb

9.11x10^-31 kilogram

Proton

+e Coulumb

9.11x10^-31 kilogram (mass of proton = mass of electron)
