The second ionisation enthalpies of elements are always higher than their first ionisation enthalpies because:

Why are the second ionisation enthalpies of group 1 elements much higher than their first ionisation enthalpies ?

The energy released during the addition of an electron to an isolated neutral atom is called electron gain enthalpy. a) Explain how electron gain enthalpy differ from electronegativity. b) The second ionisation enthalpy of an element is always greater than the first ionisation enthalpy. Give reason.

Why second ionization enthalpy is always higher than the first ionisation enthalpy for every element?

The second ionisation enthalpy of an alkaline earth metal is higher than its first ionisation enthaply. Why is it so ?

The alkaline earth metals exist as dipolar ions (M^(2+)) even though their second ionisation enthalpies are higher than those of their first ionisation enthalpies. Explain.

The second ionisation energy is always higher than the first ionisation energy because the

The second ionisation enthalpy of the alkaline earth metals is __________ than their first ionisation enthalpy.

The first ionisation enthalpy of Mg is higher than the first ionisation enthalpy of:
