Is hydrogen a molecule and or compound or element?

Answer 1

Hydrogen is an elemental gas.

It exists as the molecule ' H2 '. Structurally shown as ' H-H '.

NB Hydrogen does NOT exist as a monatomic gas.

It is NOT a compound. Compounds are combinations of atoms of different elements, e.g. water (H2O).

NB To avoid confusion. Molecules are two or more atoms combined together. They may be of the samer or different elements.

Compounds are molecules consisting of two or more DIFFERENT atoms combined together.

So molecules can be consist of two or more atoms

Compounds can be consist of two or more different atoms. Hence compounds are molecules, but molecules are not necessarily compounds ; subtle difference.

Answer 2

Hydrogen is an element because it is made up of only one type of atom, which is hydrogen itself. When two hydrogen atoms bond together, they form a hydrogen molecule (H2). So, hydrogen can exist as both an element and a molecule.

Answer 3

Hydrogen is an element. Also a molecule.
