Question

An element of mass $\mathrm{M}$ has $\mathrm{Z}$ protons and $\mathrm{N}$ neutrons. Masses of proton and neutron are $m_p$ and $m_n$ respectively. Choose the correct relation among following options

Accepted Answer

$M < Z m_p+N m_n$

Answer

$\mathrm{M} > \mathrm{Zm} m_p+\mathrm{Nm} m_n$

Answer

$\mathrm{M}=\mathrm{Zm} m_p+\mathrm{Nm}$

Answer

$\mathrm{M}$ may be greater than, less than or equal to $\mathrm{Zm} m_p+N m_n$ depending on nature of nucleus
