Atoms And Nuclei Question 185
Question: $ 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 [CBSE PMT 2001]
Options:
A) $ M<[NM_{n}+ZM_{P}] $
B) $ M>[NM_{n}+ZM_{P}] $
C) $ M=[NM_{n}+ZM_{P}] $
D) $ M=N[M_{n}+M_{P}] $
Show Answer
Answer:
Correct Answer: A
Solution:
Actual mass of the nucleus is always less than total mass of nucleons so $ M<(NM_{n}+Zm_{p}) $ .
