Question

What is Ionisation Potential?

Answer

The amount of energy required to remove the most loosely bound Electron from an isolate gaseous atom is known as Ionisation Potential, also called Ionisation Energy. It may be represented as Atom (g) + I.E→ Positive Ion (g) + Electron (g) It is expressed in terms of eV/atom or kcal/mol or kJ/mol (1 eV per atom = 23.06 kcal/mol)
