They differ in size, mass and charge.


I assume you mean the nucleus of an atom, not the nucleus of a cell.

The nucleus of an atom consists of neutrons (no charge) and protons (positive charge). Electrons orbit around the nucleus and have a negative charge.

Mass of these particles is measured in atomic mass unit (amu).
#1 "amu" = 1.66 * 10^-27 kg#
Both protons and neutrons have a mass of approximately 1 amu. Electrons are much lighter and smaller with a mass of only 0.0005 amu.
