List - I		List - II
A.	Cohesive Energy	I.	Energy required to remove electron from atom
B.	Work Function	II.	Energy required to remove electron from metal surface
C.	Electron Affinity	III.	Energy released when electron is added
D.	Ionization Potential	IV.	Energy required to separate crystal into individual atoms

• A. A-IV, B-II, C-III, D-I
• B. A-I, B-II, C-III, D-IV
• C. A-II, B-III, C-IV, D-I
• D. A-III, B-IV, C-I, D-II

Hint:

Cohesive energy separates a crystal into atoms; work function removes an electron from a metal surface.
