Phosphorus being a non-metal always forms acidic oxides like${\text{P}}_4{\text{O}}_6,{\text{P}}_4{\text{O}}_{10},$etc. whereas$\mathrm{Al}, \mathrm{Sn}$and$\mathrm{Sb}$are amphoteric elements.
$\text{A}{\text{l}}_2{\text{O}}_3,\text{S}\text{n}\text{O}$and$\text{S}{\text{b}}_2{\text{O}}_3$are amphoteric oxides i.e., they can react with both acids as well as bases.
