The energy required for the removal of an outermost electron from an isolated unipositive gaseous ion is called second ionization potential. Thus when $M g$ loses one electron, it forms $M g^{+}$ ion. The energy released during the process corresponds to first ionization potential.
When $M g^{+}$ ion loses one electron to form $M g^{2 +}$ ion, the energy released is called second ionization potential.
$M g \to M g^{+} + e^{-} Δ H =$ first ionization energy.
$M g^{+} \to M g^{2 +} + e^{-} Δ H =$ second ionization energy.
