Phosphorus being a non-metal always forms acidic oxides like {\text{P}_{4}{\text{O}_{6}, {\text{P}_{4}{\text{O}_{10}, etc. whereas and 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.
