HOMOGENEOUS SUBSTANCES
3
ELEMENTS

• ATOMS Building blocks of matter
• Each type of atom with a specific structure
  element
• 109 known specific type of atoms
• Homogeneous

4
COMPOUNDS

• Combination of elements forming a new substance
• Chemical bonding determined by the structure of
  the atoms
• Chemical bonding Chemical change
• Physical and chemical properties change
• Homogeneous

5
SOLUTIONS

• Two or more substances
• One dissolves into the other spreads evenly
  through
• Physical bonding Physical change
• Each component maintains its properties
• Homogeneous

6
HETEROGENEOUS SUBSTANCES
7
SUSPENSIONS

• One of the parts is a liquid
• The parts separate easily
• It must be shaken to unite the parts

8
COLLOIDS

• Very small particles
• Particles are spread un evenly through the
  mixture
• Tyndal effect can be used to distinguish the
  particles
• Can be separated through physical methods
  (Centrifuge)
• Gels,
