word bank: elements, compounds or mixtures

Explanation:

An element is a pure substance made of only one - type of atom. A compound is a pure substance made of two or more different types of atoms chemically combined in a fixed ratio. A mixture is a combination of two or more substances that are not chemically combined. For the drawings: In the first box of the identification part, if the circles are of different types bonded together, it's a compound. In the second box, if there are different - sized and - colored circles bonded in groups, it's also a compound. In the third box, if the circles are all of the same type, it's an element.

Answer:

Element: A pure substance made of only one type of atom. Example: Oxygen.
Compound: A pure substance made of two or more different types of atoms chemically combined in a fixed ratio. Example: Table salt (sodium chloride, NaCl).
Mixture: A combination of two or more substances that are not chemically combined. Example: Salt water (a mixture of salt and water).
For the identification part (from left - to - right assuming the first box has different atoms bonded, second box has different atoms bonded in groups, third box has same atoms): Compound, Compound, Element.
