Give the symbol, relative charge and mass of the three sub atomic particles.

Subatomic particles:

The small particles inside an atom are known as subatomic particles or fundamental particles.

There are three types of subatomic particles:

1. Electrons: Electrons are negatively charged.
2. Protons: Protons are positively charged.
3. Neutrons: Neutrons have no charge.

Symbol, relative charge and mass of electron, proton and neutron:

Sub-atomic particle	Symbol	Relative charge	Relative mass
Electron	${\mathrm{e}}^{-}$	$-1$	$0$
Proton	${\mathrm{p}}^{+}$	$+1$	$1$
Neutron	$\mathrm{n}$	$0$	$1$
