Answer
The oxides which reacts with water to form bases are called basic oxides. Metal oxides are basic as they form a base on the reaction with water. For example, $\begin{array}{l} \underset{\text{(Sodium oxide)}}{Na _2 O ( s )}+ H _2 O ( l )\longrightarrow \underset {\text{Sodium hydroxide}}{2NaOH(aq)} \end{array}$ Thus, metal oxides are basic in nature. Examples : $Na _2 O , MgO , CaO , BaO$.
