- 2. the study of substances. This includes the matter that makes them up, their properties, and the ways they interact.
- 3. The mass of the nucleus of the atom. Mass of proton and neutrons combined.
- 6. Properties that can only be determined when changes or reactions take place
- 7. Columns on the periodic table, that share chemical and physical properties
- 9. The number of protons in an element

- 13. On the left side of the periodic table. They are often shiny, conduct heat electricity, and melt at high temps.
Down
- 1. Properties that can be determined by observation
- 4. Special characteristics of matter that helps define a substance. Can be Chemical or Physical.
- 5. Along the zigzag. Could have properties of both metals and nonmetals
- 8. On the right side of the periodic table. They are usually brittle, don’t conduct, and have low density.
- 9. The smallest unit of matter that maintains its chemical identity
- 10. The smallest particle of a substance. It’s a group of atoms linked or bonded together.
