1. Before we go any further with minerals…we need to review our Chemistry!! Chapter 2 in a nut-shell

2. Matter Anything that takes up space

3. Atom The smallest particle that can exist in matter.

4. Elements Substances made up of only 1 type of atom. You can find these on the periodic table of elements.

5. Model of an atom Protons (positive) Neutrons (neutral) Electrons (negative) Protons and neutrons are found in the nucleus and electrons float outside of the nucleus in orbital.

6. Compounds Two element can combine to form a compound. Na (sodium) and CL (chlorine) combine to form salt when heat is added.

7. States of Matter There are 4 states of matter. Solid, Liquid, Gas, and Plasma

8. Density This is a physical property of matter Density=mass/volume -mass=how much matter an object has -volume=how much space an object occupies. -Density is measured in g/cm3 or g/mL
