Question

Compare a proton and a neutron w.r.t mass and charge.

Answer 1

Proton:

1. Protons are positively charged sub-atomic particles present in the nucleus of an atom.
2. The protons are denoted as ${\mathrm{p}}^{+}$.
3. Relative charge on proton is $+1$.

Neutron:

1. Neutrons are electrically neutral sub-atomic particles present in the nucleus of an atom.
2. The protons are denoted by the symbol $\mathrm{n}$.
3. Relative charge on neutron is $0$.

Subatomic particles	Charge	Mass
Proton	$1.6\times {10}^{-19}\mathrm{C}$	$1.672\times {10}^{-27}\mathrm{kg}$
Neutron	$0$	$1.674\times {10}^{-27}\mathrm{kg}$
