Question

mp and mn are masses of proton and neutron respectively. An element of mass M has Z protons and N neutrons then (A)  M > Zmp + Nmn  (B)  M = Zmp + Nmn  (C)  M < Zmp + Nmn  (D) M may be greater than less than or equal to Zmp + Nmn , depending on nature of element

When a nucleus is formed, then the mass of nucleus is slightly less than the sum of the mass of Z protons and N neutrons. ie M < (Zmp+Nmn)

Q. $m_{p}$ and $m_{n}$ are masses of proton and neutron respectively. An element of mass $M$ has $Z$ protons and $N$ neutrons then

$M > Z m_{p} + N m_{n}$

$M = Z m_{p} + N m_{n}$

$M < Z m_{p} + N m_{n}$

M may be greater than less than or equal to $Z m_{p} + N m_{n}$ , depending on nature of element

Q. mp​ and mn​ are masses of proton and neutron respectively. An element of mass M has Z protons and N neutrons then

M>Zmp​+Nmn​

M=Zmp​+Nmn​

M<Zmp​+Nmn​

M may be greater than less than or equal to Zmp​+Nmn​ , depending on nature of element
