Mn and Mp represent mass of neutron and ...

`M_n` and `M_p` represent mass of neutron and proton respectively. If an element having atomic mass `M` has `N-`neutron and `Z`-proton, then the correct relation will be :

A

`M lt [NM_(n) + ZM_(P)]`

B

`M gt [NM_(n) + ZM_(P)]`

C

`M= [NM_(n) + ZM_(P)]`

D

`M= N[M_(n) + M_(P)]`

Text Solution

Verified by Experts

The correct Answer is:
A
Actual mass of nucleus is always less than total mass of nucleons `M lt (NM_(n) + ZM_(P))`
