Solution

The correct option is A n=2,l=1,m=0
A neutral atom contains an equal number of electrons and protons. So, the charge of an electron and the proton are equal in magnitude but opposite in sign.

The charge of an electron is $- 1.6 \times 10^{- 19} C$ .

The charge of a proton is $+ 1.6 \times 10^{- 19} C$ .
