$-3, +3$ and $+5$

Vedclass · Answer

(A) The three important oxidation states of phosphorus are $-3, +3$,and $+5$.$1$. $-3$: Phosphorus has $5$ electrons in its valence shell $(3s^2 3p^3)$. To attain a stable octet configuration,it gains $3$ electrons,resulting in a $-3$ oxidation state.$2$. $+3$: Phosphorus uses its $3$ unpaired $p$-electrons for bonding,resulting in a $+3$ oxidation state.$3$. $+5$: Phosphorus uses all $5$ valence electrons ($3s^2$ and $3p^3$) for bonding,resulting in a $+5$ oxidation state.
