The first ionization energy is the energy it takes to remove one electron from an atom, the second ionization energy is the energy it takes to remove a second electron from the atom, and so on.M(g)→M(g)++e−;ΔH=100 eV M(g)→M(g)2++2e−;ΔH=250 eVEnergy required to remove first electron from M is 100 eV so the (IE)1 or M(g) is 100 eV.Energy required to remove two electrons from M is 250 eV so we can say that energy required to remove an electron from M+ is 150 eV. So, the(IE)1 of M+(g) is 150 eV.Energy required to remove the second electron from M is 150 eV so the (IE)2 or M(g) is 150 eV.

Detailed Solution

The first ionization energy is the energy it takes to remove one electron from an atom, the second ionization energy is the energy it takes to remove a second electron from the atom, and so on.

$M_{(g)} \to M_{(g)}^{+} + e^{-}; ΔH = 100 eV M_{(g)} \to M_{(g)}^{2 +} + 2 e^{-}; ΔH = 250 eV$

Energy required to remove first electron from M is 100 eV so the (IE)₁ or M(g) is 100 eV.
Energy required to remove two electrons from M is 250 eV so we can say that energy required to remove an electron from M+ is 150 eV. So, the(IE)₁ of M⁺(g) is 150 eV.
Energy required to remove the second electron from M is 150 eV so the (IE)₂ or M(g) is 150 eV.
