Difference Between Elements, Compounds, Mixtures
| Property | Elements | Compounds | Mixtures |
| Composition | Consists of only one type of atom | Consists of two or more types of atoms chemically bonded together | Consists of two or more substances physically mixed together, but not chemically bonded |
| Breakdown | Cannot be broken down into simpler substances | Can be broken down into simpler substances by chemical means | Components retain their individual properties and can be separated by physical means |
| Chemical Formula | Represented by chemical symbols | Have unique chemical formulas | No fixed chemical formula |
| Examples | Hydrogen (H), Oxygen (O2), Iron (Fe) | Water (H2O), Carbon dioxide (CO2), Sodium chloride (NaCl) | Air (a mixture of gases), Seawater (a mixture of water and salts), Salad dressing (a mixture of oil and vinegar) |
