Question

Consider the following changes :
(1) $\mathrm{M}(\mathrm{s}) \longrightarrow \mathrm{M}(\mathrm{g})$
(2) $\mathrm{M}(\mathrm{s}) \longrightarrow \mathrm{M}^{2+}(\mathrm{g})+2 \mathrm{e}^{-}$
(3) $\mathrm{M}(\mathrm{g}) \longrightarrow \mathrm{M}^{+}(\mathrm{g})+\mathrm{e}^{-}$
(4) $\mathrm{M}^{+}(\mathrm{g}) \longrightarrow \mathrm{M}^{2+}(\mathrm{g})+\mathrm{e}^{-}$
(5) $\mathrm{M}(\mathrm{g}) \longrightarrow \mathrm{M}^{2+}(\mathrm{g})+2 \mathrm{e}^{-}$
The second ionization energy of $\mathrm{M}$ could be calculated from the energy values associated with:

Aicharya · Accepted Answer

Second ionization energy is amount of energy required to take out an electron from the monopositive cation.
