Yes

Vedclass · Answer

(A) The ionisation energy of an isolated free atom is different from its value in a crystalline lattice.In a crystalline lattice,each atom is surrounded by other atoms.The potential energy of an electron in a crystal is influenced by the electric fields of all the neighboring atoms in the periodic lattice.This interaction modifies the energy levels of the electrons,causing the ionisation energy to differ from that of an isolated atom.

Is the ionisation energy of an isolated free atom different from the ionisation energy for the atoms in a crystalline lattice?
