Matter and Chemistry

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
12. Organized in the Periodic Table. Has one kind of atom that cannot be broken down, Compounds- Two or more types of atoms or elements chemically bonded together and Mixtures- Substances that contain more than two elements or compounds, but are not chemically bonded togetherp24-25
13. On the left side of the periodic table. They are often shiny, conduct heat electricity, and melt at high temps.

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.
11. Anything that has mass and takes up space. Three main phases of matter are solids, liquids, and gases.
