Solution

Atoms are made of three subatomic particles namely electrons, protons, and neutrons.
There is a small, dense, central region of an atom where the majority of the mass is concentrated known as the nucleus.
Positively charged protons and neutral neutrons are present inside the nucleus.
The negatively charged electrons are revolving around the nucleus in a definite circular path known as orbits or energy levels.
Subatomic particles Symbols Relative charges
Proton $p$ $+ 1$
Electron $e$ $- 1$
Neutron $n$ $0$
