Assuming the equilibrium separation of two atoms to be 2.8 A and dissociation energy (energy
which will be given out in the process of the formation of a crystal by bringing neutral atoms from
infinity to the position of equilibrium or it is defined as the energy required to separate the atoms
from equilibrium separation to an infinite distance) is 8xl0
