What is matter?

• Matter anything that has mass and takes up
  space.

Matter

• It is broken down into two categories pure
  substances and mixtures.

4

• Pure Substance Composition and properties never
  change from one sample to the next
• Ex Table salt, Oxygen, pure water

5

• Mixtures Composition and properties can change
  from one sample to the next
• Ex Salsa, lemonade, milk

6

• Element pure substance that cannot be broken
  down into simpler form by ordinary means
• Contain only 1 type of atom
• Atom smallest particle of an element that keeps
