# Can a compound only contain one kind of atom?

Apr 24, 2018

No.

#### Explanation:

By definition a compound is composed of two or more different elements chemically bonded, which is same as saying more than one kind of atom.

Examples of compounds:

$\text{H"_2"O}$

$\text{NaCl}$

$\text{MgSO"_4}$

$\text{CH"_4}$

Examples of molecules that are not compounds but contain more than one atom, each of which is the same kind of atom. These are diatomic elements.

$\text{H"_2}$

$\text{N"_2}$

$\text{O"_2}$

$\text{F"_2}$
