Vedclass · Answer

(B) The first ionization enthalpy values are as follows:$B$: $801 \ kJ/mol$$Al$: $577 \ kJ/mol$$Ga$: $579 \ kJ/mol$Statement $I$: The decrease from $B$ to $Al$ is $801 - 577 = 224 \ kJ/mol$,while the change from $Al$ to $Ga$ is $579 - 577 = 2 \ kJ/mol$ (an increase). Thus,the decrease from $B$ to $Al$ is indeed much larger than the change from $Al$ to $Ga$. Statement $I$ is correct.Statement $II$: The electronic configuration of $Ga$ $(Z=31)$ is $[Ar] \ 3d^{10} \ 4s^2 \ 4p^1$. The $3d$ orbitals are completely filled. Statement $II$ is correct.
