Metallic oxides are basic in nature because they react with dilute acids to form salt and water. Group 1 & 2 oxides are highly alkaline in nature that is why group 1 called alkaline metals and group 2 called Alkaline Earth metals.

How metal oxides are basic?

Metals with high oxidation states form oxides whose bonds have a more covalent nature. ... Ionic metal oxides react with water to give hydroxides (compounds containing the OH⁻ ion) and resultant basic solutions, whereas most nonmetal oxides react with water to form acids and resultant acidic solutions (see the table).

What is the nature of metallic oxide in nature?

Metal oxides are basic nature. Some are amphoteric.
