The sun of the number of neutrons and protons in the isotope of hydrogen is

A

`6`

B

`5`

C

`4`

D

`3`

Text Solution

Verified by Experts

The correct Answer is:
D
For protium (`_(1)^(1)H)`, the sun is `(0+1=)=1`, for deuterium (`_(1)^(2)H)`, the sun is `(1+1=)=2`, and for tritium (`_(1)^(3)H)`, the sun is `(2+1=)=3`.
