Pure Substances
Pure substances, like elements or compounds such as
diamond or carbon dioxide, consist of a single type of entity
and cannot be broken down further through chemical or
physical methods. 
Elements, in particular, are pure materials made up of only one
type of atom, ensuring consistency in composition and
properties.
