metal oxides

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> The reaction between a metal and oxygen gives metallic oxide as a product. These metallic oxides upon reaction with water form bases. Hence, the metallic oxides are considered as basic oxides. For example:

$2Mg+O_2\to 2MgO\stackrel{H_{2}O}{\to }Mg\left(O{H}_2\right)$
