What is Chemistry?
Chemistry is the study of the composition and
properties of matter.
3
What is matter?
Matter is anything that has mass and takes up
space.
4
Matter surrounds us in the form of solids,
liquids, and gases.
All matter, regardless of its size, shape, or
color, is made of particles that are too small to
be seen by the unaided eye.
5
Atoms

• ATOM-the basic unit of matter.
• An atom is made up of 3 parts
• Protron ( charge)
• Neutron (no charge)
• Electron (- charge)

6
Elements

• ELEMENT-the specific name of an atom.
• An element is distinguished by its atomic number
  (the number of protons it has).

7
Molecules

• MOLECULE- made up of two or more atoms that are
  held together through bonds.

• Bonds are attractions between atoms that tightly
  hold the molecule together.

8
A Simple Molecule

• Water (H20)
• 2 hydrogen atoms
• 1 oxygen atom

9
Another Simple Molecule

• Ethane (C2H6)
• 2 carbon atoms
• 4 hydrogen atoms

10
A Polymer More Complex
The polymer polyethylene consists of many
ethane molecules.
11
What is a Polymer?

• Polymers are made of many molecules strung
  together to form really long chains.
• Polymers can occur in
  nature or they can be
  man-made.

12
What is a polymer?

• These long polymer chains are formed by teeny
  tiny molecules called monomers.
• A single polymer molecule is made out of hundred
  of thousands (or even millions!) of monomers!

13
Today we will

• Measure ingredients in a formula.
• Create a polymer.
• Convert fractions to decimals and percents.
• Have fun with math and science!
