Question

what type of oxides are formed by metals and nonmetals

Answer 1

Answer:

Metals form basic oxides while non metals form acidic oxides.

Explanation:

• Metals and non metals can react with oxygen to form oxides.

• Metals like Na, Mg, Fe, Ca react with oxygen to give Basic oxides. Basic oxides dissolve in water to form bases or alkalis. This means that they act as bases and neutralize acids to give salt and water. For example,

        Calcium +  oxygen ⇒ Calcium oxide

        Calcium oxide + water ⇒ Calcium hydroxide.

• Non metals like C, S, P react with oxygen to give acidic oxides. Acidic oxides dissolve in water to form acids. This means that they act as acids and neutralize bases  to give salt and water. For example,
•         Carbon + oxygen ⇒ Carbon dioxide
•         Carbon dioxide + water ⇒ Carbonic acid
