Question

The charge on the proton.

Answer 1

Protons:

1. Protons are positively charged sub-atomic particles which are present in the nucleus of an atom.
2. The charge on a proton is equal and opposite to the charge on an electron.
3. The charge on the proton is $1.6\times {10}^{-19}\mathrm{C}$ which is very very small.
4. Thus, the charge on the proton is taken as a unit positive charge i.e. $+1$.

Thus, the charge on the proton is $+1$.
