An element is a pure substance that cannot be broken down into simpler substances by chemical means. It consists of only one type of atom. Examples of elements include oxygen, gold, and carbon.
A compound is a substance composed of two or more elements that are chemically bonded together in a fixed ratio. Compounds can be broken down into their constituent elements by chemical reactions. Examples of compounds include water (H2O) and sodium chloride (NaCl).
A mixture is a combination of two or more substances that are physically mixed together but not chemically bonded. Mixtures can be separated into their individual components by physical means, such as filtration or distillation. Examples of mixtures include saltwater, air, and trail mix.

Element
- A pure substance that cannot be broken down into simpler substances by chemical means.
- Consists of only one type of atom.
- Represented by a single chemical symbol (e.g., He, O, Fe).
Compound
- A pure substance composed of two or more different elements that are chemically combined in a fixed ratio.
- Can be broken down into its constituent elements by chemical means.
- Represented by a chemical formula that indicates the types and proportions of the elements (e.g., H2O, NaCl, C6H12O6).
Mixture
- A physical combination of two or more substances that are not chemically combined.
- Can be separated into its constituent substances by physical means (e.g., filtration, distillation).
- Does not have a definite composition or chemical formula.
Key Differences:
| Feature | Element | Compound | Mixture |
|---|---|---|---|
| Composition | Single type of atom | Different elements in fixed ratio | Different substances not chemically bonded |
| Structure | Homogeneous | Homogeneous | Heterogeneous or homogeneous |
| Properties | Determined by the element itself | Determined by the elements and their bonding | Variable, depends on composition |
| Separation | Cannot be separated | Can be separated by chemical means | Can be separated by physical means |
| Chemical identity | Defined by atomic number | Defined by chemical formula | No definite chemical identity |
