Oxides of metals are what kind of oxides?

Explanation:
Metal oxides behave as basic oxides. Their oxide ion (O2−) tends to react with water to form metal hydroxides, which are alkaline. For example, sodium oxide dissolves in water to give sodium hydroxide, a strong base, and magnesium oxide reacts with water to form magnesium hydroxide, a basic solution. They also react with acids to form salts and water, which is another hallmark of basic oxides. While some metal oxides (like aluminum oxide) can be amphoteric, the common trend for oxides of metals is basic behavior, in contrast to non-metal oxides that are typically acidic.
