Elements, Compounds and Mixtures interactive worksheet | Live ... - Free Printable

To solve this problem, we need to look at each box and decide what kind of matter it shows based on the particles inside.

Here is the key to remember:
* Element (A): Only one type of atom (one color). They can be alone or bonded to the same color.
* Compound (B): Two or more different types of atoms (different colors) bonded together in a specific pattern. Every particle looks exactly the same.
* Mixture of elements (C): Different types of single atoms or elemental molecules mixed together, but nothing is bonded to a *different* color.
* Mixture of compounds (D): Different types of compound molecules mixed together.
* Mixture of elements and compounds (E): A mix of pure elements (single colors) and compounds (bonded different colors).

Let's go through them one by one:

1. Box 1: All particles are identical. Each particle has 1 black atom and 2 white atoms bonded together. Since they are all the same compound, this is a Compound. -> B
2. Box 2: There are individual black atoms and individual white atoms floating around. They are not bonded to each other. This is a mix of two different elements. -> C
3. Box 3: We see some particles that are compounds (black and white bonded) and some particles that are just pairs of white atoms (an element). This is a mix of both. -> E
4. Box 4: We see two different shapes of molecules. One shape has 2 black/3 white, the other has 1 black/2 white. Both are compounds, but they are different from each other. -> D
5. Box 5: All particles are single black dots. Just one type of atom. -> A
6. Box 6: All particles are identical. Each has 1 white atom and 3 black atoms. It is a pure substance made of compounds. -> B
7. Box 7: All particles are pairs of white atoms bonded together. Even though they are pairs, they are only one type of atom (white). So it is an element. -> A
8. Box 8: We see single black atoms, single white atoms, AND molecules made of 1 black/2 white atoms. This is a mix of elements and a compound. -> E
9. Box 9: We see single black atoms (element) and pairs of white atoms (element). No compounds here. Just a mixture of two elements. -> C
10. Box 10: We see pairs of white atoms (element) and molecules with 1 black/2 white atoms (compound). This is a mix of elements and compounds. -> E
11. Box 11: All particles are identical. Each is a chain of black and white atoms. Since every particle is the same compound, it is a pure compound. -> B
12. Box 12: All particles are identical. Each has 1 black and 2 white atoms. Pure compound. -> B
13. Box 13: We see two different types of molecules. One type is 2 black/4 white, the other is 3 black/3 white. Both are compounds, but different ones. -> D
14. Box 14: We see three different things: molecules with 1 black/3 white, molecules with 1 black/2 white, and single black atoms. This is a complex mix of elements and compounds. -> E
15. Box 15: We see two different types of molecules. One is 1 black/3 white, the other is 1 black/2 white. Both are compounds. -> D
