4. BASIC CHEMISTRY
Matter - Solid, Liquids, Gas
Elements – Atoms & Particles
Molecules & Compounds

5. Chemistry

6. Matter
Matter = any material
substance with Mass
& Volume

7. States of Matter- 3 State
Solid
Liquid Gas

8. Solid
Definite Shape
Definite Volume

9. Liquid
Indefinite Shape –
takes the shape of the
container
Definite Volume

10. Gas
Indefinite Shape –
takes the shape of
the container
Indefinite Volume –
can expand and be
compressed

11. Elements & Examples
One of the 100+ pure substances
that make up everything in the universe
C = Carbon Na = Sodium
O = Oxygen Ca = Calcium
H = Hydrogen K = Potassium
N = Nitrogen I = Iodine
S = Sulfur Cl = Chlorine

12. Atom
The smallest particle making
up elements

13. Sub-Atomic Particles
Protons p+ - positive charge,
in nucleus
Neutrons n0 – no charge,
in nucleus
Electrons - e- negative charge,
orbiting around
nucleus

14. Drawing an Atom of Carbon
Nucleus:
Electrons
6C
12.011
Atomic no:= no: of p+ or no: of e-
Carbon has 6 p+ and 6 e-
Carbon has 6 n0
Atomic Mass – Atomic no: = no: of n0

Structural formula

16. Compounds
Compounds - 2 or more elements
chemically combined to form
a new substance with
new properties
Properties – The way a chemical
substance looks and behaves

17. Compounds
Compounds are made of 2 or
more different atoms combined
to form Molecules
H + O H2O
H
O
H
Chemical formula lists the
number of different atoms
in a single molecule
Structural formula shows
the arrangement of the
atoms in a single molecule

18. Examples of Organic
Compounds
C, H + O Carbohydrates – Sugars,
Starch & Cellulose
C, H + O Lipids – Fats & Oils
C, H, O, N, &
Proteins
sometimes P + S
C, H, O, N, + P Nucleic Acids – DNA & RNA

that’s all folks!
