Elements : Silver and hydrogen

An element is a pure chemical substance that contains one kind of atom only.

Here, Ag ( silver ) contains only one atom and H2 ( hydrogen ) contains two atoms of same kind.

So, they are elements.

Compounds : methane and water.

A compound is a chemical substance that combines two or more elements.

Here, CH4 ( methane ) contains five atoms of two different elements carbon and hydrogen and H2O ( water ) contains three atoms of two different elements hydrogen and oxygen.

So, they are called compounds.
