Question

Zinc shows only one oxidation slate. Explain.

✓

Answer

The electronic conliguration of zinc is, ${ }_{30} Z n \ Is^2 2 s^2 2 p^6 3 s^2 3 p^6 3 d^{10} 4 s^2$ or $[ Ar] 3 d^{10} 4 s^2$.
Due lo loss of two electrons from $4s$ suhshell $Zn$ shows oxidation state $+2$. with elcctronic configuration. $[ Ar ]^{18} 3 d^{10}$.
Since $Zn ^{+2}$ acquires an extra stability of completely fIlled $3 d^{10}$ orbital. it shows only one oxidation state $+ 2.$
