Vedclass · Answer

(B) The atomic/ionic size depends on the effective nuclear charge $(Z_{eff})$ and the number of shells. For ions,as the positive charge increases,the $Z_{eff}$ increases,leading to a decrease in ionic size. Thus,$Zn^{2+}$ is smaller than $Cu^{+}$. For neutral atoms,the size increases down a group. Since $Ag$ is in the $5^{th}$ period and $Cu$ is in the $4^{th}$ period,$Ag > Cu$. Comparing the species: $Zn^{2+}$ ($Z=30$,$28$ electrons),$Cu^{+}$ ($Z=29$,$28$ electrons),$Cu$ ($Z=29$,$29$ electrons),and $Ag$ ($Z=47$,$47$ electrons). The correct order of size is $Zn^{2+} < Cu^{+} < Cu < Ag$.
