Reactions of Oxygen with Elements

The video tutorial explores the chemical properties of oxygen, focusing on its reactions with metals, non-metals, and compounds. It explains how oxygen forms basic oxides with metals and acidic oxides with non-metals. The process of corrosion, particularly rusting of iron, is discussed, along with the formation of ozone from oxygen through a silent electric discharge.

What type of compound is formed when oxygen reacts with most metals?

• Acidic oxide

• Neutral compound

• Basic oxide

• Covalent compound

What happens when group one metals react with excess oxygen?

• They form basic oxides

• They do not react

• They form peroxides

• They form acidic oxides

How do non-metals react with oxygen?

• They form ionic compounds

• They do not react

• They form covalent compounds

• They form metallic oxides

What is the nature of non-metallic oxides formed when non-metals react with oxygen?

• Acidic

• Basic

• Amphoteric

• Neutral

What is formed when SO2 dissolves in water?
