What is the correct orbital box diagram for the ground state electron configuration of Ni? a. \( [A x] \frac{\uparrow \downarrow \uparrow \downarrow \uparrow \downarrow \uparrow \downarrow \downarrow}{3 d} \frac{\uparrow \downarrow}{4 s} \) c. \( [A r] \frac{\uparrow \downarrow \uparrow \downarrow \uparrow \downarrow \uparrow \downarrow \uparrow \downarrow}{3 d} \) 4s d. \( [A r] \quad \)\begin{tabular}{|l|l|l|l|l|} \hline\( \uparrow \) & \( \uparrow \) & \( \uparrow \) & \( \uparrow \) & \( \uparrow \) \\ \hline \( 3 d \) & \( \uparrow \downarrow \) \\ \hline & & \\ \( 4 s \) \end{tabular} e. \( [A r] \frac{\uparrow \downarrow \uparrow \downarrow \uparrow \downarrow \downarrow \downarrow \downarrow \uparrow}{3 d} \frac{\uparrow}{4 s} \) An atom of which of the following elements has the smallest atomic radius? a. \( \mathrm{Rb} \) b.I c. \( \mathrm{Sb} \) d. Te e. \( \mathrm{Sn} \)
