Vedclass · Accepted Answer

The ionization energy of hydrogen is too high for the group of alkali metals,but too low for the halogen group.

Vedclass · Answer

(A) The ionization energy of hydrogen is $1312 \ kJ \ mol^{-1}$,which is significantly higher than that of alkali metals (e.g.,$Li = 520 \ kJ \ mol^{-1}$) and significantly lower than that of halogens (e.g.,$F = 1681 \ kJ \ mol^{-1}$).Therefore,hydrogen does not fit perfectly into either group based on its ionization energy.

Which of the following explanations is best for not placing hydrogen in either the group of alkali metals or halogens?
