Dioxygen directly reacts with nearly all metals annd non-metals except some metals (e.g., Au, Pt) and some noble gases and form oxide(s). Oxides can be simple (e.g., MgO, `Al_(2)O_(3)`) or mixed `(Pb_(3)O_(4),Fe_(3)O_(4))`. Simple oxides can be classified on the basic of their acidic, basic or amphoteric character. an oxide that combines with water to give an acid is termed acidic oxide (i.e., `SO_(2),Cl_(2)O_(7),CO_(2),N_(2)O_(5)`). for example, `SO_(2)` combines with water to give `H_(2)SO_(3)`, an acid.
