An element undergoes a reaction as shown :
\( X+2 e^{-} \longrightarrow X^{2-} \), energy released math xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymo=/momn30/mnmo./momn87/mnmo /momieV/mimo//momiatom/mi/math. If the energy released, is used to dissociate \( 4 \mathrm{~g} \) of \( \mathrm{H}_{2} \) molecules, equally into \( \mathrm{H}^{+} \)and \( \mathrm{H}^{*} \), where \( \mathrm{H}^{*} \) is excited state of \( \mathrm{H} \) atoms where the electron travels in orbit whose circumference equal to four times its de Broglies wavelength. Determine the least moles of \( X \) that would be required :
