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

Why the second ionization enthalpy is greater than the first ionization enthalpy?

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

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

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

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

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 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.

The first ionization enthalpy of magnesium is lower than the first ionizxation enthalpy of

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