Question

What is the nature of most of the metali and non metalic oxides?

Answer 1

Non-metals react with oxygen in the air to produce non-metal oxides. Here are two examples for the non-metals carbon and sulphur. Non-metal oxides such as sulphur dioxide and nitrogen oxide are responsible for acid rain. They dissolve in the water in the clouds to form acidic solutions.

Answer 2

Metal oxides are always basic in nature. For example, Magnesium Oxide is a metallic oxide. It will be basic because on adding water to it it will become Mg(OH)2 (Magnesium Hydroxide) which is a base!!!!! Non Metallic oxides are always acidic in nature.
