Ionisation Energy Quiz

Ionisation energy is the energy required to form 1 mol of a positive ion by removal of 1 mol of electron in gas phase.

The unit of ionisation energy is joules (J) or kilojoules per mole (kJ/mol).

Ionisation energy measures the energy required to remove an electron from a neutral atom or molecule to form a positive ion.
