MASS DEFECT:-

==============

The DIFFERENCE in the sum of masses of all nucleons present in a nucleus and the mass of the nucleus is CALLED MASS DEFECT

➭When a number of protons and neutrons (nucleons) combine together to form a nucleus , a small fraction of their masses is LOST which appears in the form of $\textbf{binding energy}$

LET,

$m_{p}$ ➭ $\green{\texttt{mass of proton}}$

$m_{n}$ ➭ $\green{\texttt{mass of neutron}}$

$m_{N}$ ➭ $\green{\texttt{mass of nucleus}}$

Z ➭ $\green{\texttt{atomic number}}$ = no. Of protons

A ➭ $\green{\texttt{atomic weight}}$ =

➭ $\textbf{number of protons}$ + $\textbf{number of neutrons}$

Mass defect,

Δm ➭ [Z × $m_{p}$ + (A -Z ) $m_{n}]$ - $M_{N}$ .

$\green{\textbf{Binding energy}}$ ➭

It is the energy with which nucleons are bound $\green{\texttt{in the nucleus}}$ . It is measured by the WORK done to separate the nucleons on infinite distance apart from the nucleus so that they may not interact with each other.
