Many other elements, such. as most other nonmetals (O2, N2, S8, P4, etc.) occur as molecules. 2.6 Compounds contain atoms from two or more elements, thus the smallest unit must contain at least a pair of atoms. 2.7 Mixtures have variable composition; therefore, the amounts may vary. Compounds, as pure substances, have. constant composition, thus their composition cannot vary.
Pure substances will have a constant appearance, colour and density throughout the sample. Pure substances have constant chemical composition, eg, 1  pure water (H2O) is always composed of 2 hydrogen atoms and 1 oxygen atom chemically bonded.  pure gold (Au) is only made up of gold atoms.
