Describe the mass and charge of particles you find in the nucleus and in the electron cloud.

Proton is the positively charged particle with a charge equivalent to  1.6×10−19C .

Neutron is a neutral charged particle i.e. zero charge.

Electrons are negatively charged particle with a charge equivalent to  −1.6×10−19C .

Protons and Neutrons are inside the nucleus of an atom and contribute to the most of the mass of the atom. Electrons are revolving around the positively charged nucleus in quantized energy shells.
