Vedclass · Answer

(A) To match the ionization energies $(IE)$,we look at the valence electrons and the jump in energy after removing all valence electrons:$1$. $H$ $(1s^1)$: Only $1$ electron,so $IE_1 = 1312 \ kJ \ mol^{-1}$ (matches $A$ approx $1510$).$2$. $Li$ $(1s^2 2s^1)$: $1$ valence electron,large jump after $IE_1$. $IE_1=520, IE_2=7300$ (matches $B$ $495, 6500, 10200$).$3$. $Be$ $(1s^2 2s^2)$: $2$ valence electrons,large jump after $IE_2$. $IE_1=899, IE_2=1757, IE_3=14848$ (matches $C$ $840, 1630, 13100$).$4$. $B$ $(1s^2 2s^2 2p^1)$: $3$ valence electrons,large jump after $IE_3$. $IE_1=801, IE_2=2427, IE_3=3660$ (matches $D$ $600, 2050, 3100$).Thus,the correct match is $A-1, B-2, C-3, D-4$.
