Vedclass · Answer

(D) The isotopes of hydrogen are Protium $(_{1}^{1}H)$,Deuterium $(_{1}^{2}H)$,and Tritium $(_{1}^{3}H)$.For Protium $(_{1}^{1}H)$: Number of protons $(p)$ = $1$,Number of neutrons $(n)$ = $0$. Sum $(n+p)$ = $1$.For Deuterium $(_{1}^{2}H)$: Number of protons $(p)$ = $1$,Number of neutrons $(n)$ = $1$. Sum $(n+p)$ = $2$.For Tritium $(_{1}^{3}H)$: Number of protons $(p)$ = $1$,Number of neutrons $(n)$ = $2$. Sum $(n+p)$ = $3$.The sum of the number of protons and neutrons for all isotopes is $1 + 2 + 3 = 6$.

The sum of the number of protons and neutrons in all isotopes of hydrogen is .......
