Not all elements are pure substances, and not all pure substances are elements.
1. **Elements**: These are the simplest forms of matter and consist of only one type of atom. An element can be a pure substance as it cannot be broken down into simpler substances by chemical means.
2. **Pure Substances**: A pure substance can be either an element or a compound. A pure substance has a uniform and definite composition. Compounds, which are made up of two or more elements chemically combined in fixed proportions (like water, \(H_2O\)), are also considered pure substances.
Thus:
- **All elements are pure substances** because they consist of a single type of atom and have a uniform composition.
- **Not all pure substances are elements** because compounds (which are made up of two or more elements) are also classified as pure substances.
In summary, while all elements qualify as pure substances, pure substances can include both elements and compounds.
