1. MATTER
What is Matter?

2. CHEMISTRY
What things are made of, what their properties are and how the interact and change

3. MATTER
Anything that has mass and occupies space (volume).

4. Matter

5. How is matter built? 1st we start with atoms
Atoms are the smallest unit of an elements that retain the properties of that element

6. Structure of Matter
Atoms of the same kind make up elements. Elements can’t be broken down chemically into simpler substances
2 or more elements chemically come together to form compounds.

7. Types of compounds Non-metal + non-metal
When two or more non-metal elements combine to form molecules.
Diatomics
Diatomic means 2
Some non-metal elements only combine with each other

8. C6H10N2O2 Chemical Formulas Carbon (C) – 6 Hydrogen (H) – 10
Chemical Formulas show how many elements are in a compound.
The letter is the symbol for the atom
The subscript shows the number of atoms
C6H10N2O2
Carbon (C) – 6
Hydrogen (H) – 10
Nitrogen (N) – 2
Oxygen (O) – 2

9. Mixtures
Pure Substances are the same “make-up” throughout the substance.
2 types of pure substances
1) elements
2) compounds
Mixtures are made from two or more pure substances.
1) element + element
2) element + compound
3) compounds + compounds

10. Types of Mixtures Heterogenous-different Homogenous-same
Mixtures that you can see differences in substances
Sometimes called solutions
No “visible” differences in substances.
