Answer

Brief Explanations:

Elements are made of one - type of atom (e.g., Oxygen, Gold). Compounds have two or more atoms chemically bonded (e.g., Water, Carbon dioxide). Mixtures are two or more substances physically mixed, can be easily separated, and are not pure substances (e.g., Salad, Air, Saltwater). Their properties are different from individual parts.

Answer:

Examples: Oxygen (O), Gold (Au): Elements Can be easily separated into individual parts: Mixtures Made of only one type of atom: Elements Examples: Water (H₂O), Carbon dioxide (CO₂): Compounds Examples: Salad, Air, Saltwater: Mixtures Properties are different from its individual parts: Compounds, Mixtures Is NOT considered a pure substance: Mixtures Two or more separate substances physically mixed: Mixtures Two or more atoms chemically bonded: Compounds
