Question

Maximum amount of energy lies in...........

Answer 1

Answer:

Ionization Enthalpy :

It is the amount of energy required to remove an electron from an isolated gaseous atom of an element to form positive gaseous ion in its ground state.

It is more difficult to remove an electron from positive ion than from neutral or negative atom.

Hence, removal of electron fromM

+2

is more difficult and involves maximum amount of energy than their given transitions.
