Vedclass · Answer

(A) The maximum oxidation state of an element is equal to the number of valence electrons in its outermost shell. For phosphorus $(Z = 15)$,the electronic configuration is $[Ne] 3s^2 3p^3$,so it has $5$ valence electrons,giving a maximum oxidation state of $+5$.The minimum oxidation state is equal to the number of electrons required to achieve the nearest noble gas configuration. Phosphorus needs $3$ electrons to complete its octet,resulting in a minimum oxidation state of $-3$.Therefore,the range of oxidation states for phosphorus is $-3$ to $+5$.
