Solution

The correct option is A
Oxides

Metals react with oxygen to form metal oxides, which are usually basic and in some cases, amphoteric in nature.

Valency 1 $\to 4 M + O_{2} \to 2 M_{2} O$
Valency 2 $\to 2 M + O_{2} \to 2 M O$
Valency 3 $\to 4 M + 3 O_{2} \to 2 M_{2} O_{3}$

A metal A reacts with oxygen to form a metallic oxide AO, this oxide reacts with moisture and carbon dioxide of the atmosphere to form basic carbonate. metal a prevent rusting of iron .identify metal A?

as you said metals and non-metals react with oxygen to produce their oxides ,which are basic and acidic in nature

for example

magnesium reacts with oxygen to form magnesiumoxide but why then a non-metal like sulphur react with oxygen and form sulphur dioxide why not sulphur oxide??

Metals react with oxygen in air to form _________.

The correct option is A Oxides Metals react with oxygen to form metal oxides, which are usually basic and in some cases, amphoteric in nature. Valency 1 →4M+O2→2M2O Valency 2 →2M+O2→2MO Valency 3 →4M+3O2→2M2O3

The correct option is A
Oxides

Metals react with oxygen to form metal oxides, which are usually basic and in some cases, amphoteric in nature.

Valency 1 $\to 4 M + O_{2} \to 2 M_{2} O$
Valency 2 $\to 2 M + O_{2} \to 2 M O$
Valency 3 $\to 4 M + 3 O_{2} \to 2 M_{2} O_{3}$
