What is the energy (in J ) required for the following process

Question

What is the energy (in J ${atom}^{- 1}$ ) required for the following process?

$L i^{2 +} (g) ⟶ L i^{3 +} (g) + e^{-}$

(Take the ionisation energy for the H atom in the ground state as $2.18 \times 10^{- 18}$ J ${atom}^{- 1}$ ) [2026]

$E_{{Li}^{2 +} / {Li}^{3 +}} = E_{H / H^{+}} \times Z^{2}$

$E_{{Li}^{2 +} / {Li}^{3 +}} = 2.18 \times 10^{- 18} \times 3^{2} {J atom}^{- 1}$

$E_{{Li}^{2 +} / {Li}^{3 +}} = 1.962 \times 10^{- 17} {J atom}^{- 1}$
