• Solid - Maintains shape and volume

12
The States of Matter

• Solid - Maintains shape and volume
• Liquid - Maintains volume, takes the shape of
  the container

The States of Matter

• Solid - Maintains shape and volume
• Liquid - Maintains volume, takes the shape of
  the container
• Gas - No definite volume, takes the shape
  of its container

14
MATTER

• Pure substance - Has fixed composition and
  distinct properties

The Chemical Element

• The letters on the periodic table are like the
  alphabet to chemists

23
The Chemical Element

• The letters on the periodic table are like the
  alphabet to chemists
• Each Element has distinct properties

24
The Chemical Element

• The letters on the periodic table are like the
  alphabet to chemists
• Each Element has distinct properties
• When elements combine, they are written with
  subscripts indicating how many of each element
  there is.

• Each Element has distinct properties
• When elements combine, they are written with
  subscripts indicating how many of each element
  there is.
• To explain how elements react, a chemical
  equation is used

• If two of the same element combine, it is called
  a diatomic molecule. Like - Cl2 O2 N2
