classification of matter

Classification of Matter

• Basic units of matter

• Have mass and volume

• Contain subatomic particles:

  • Protons

  • Neutrons

  • Electrons

​

​Atoms

​

• Made from one type of atom

• Cannot be broken down by chemical or physical means

• Found on the periodic table

​

​Elements

Fill in the Blanks

• Created when 2 or more elements chemically combine by sharing or transferring their electrons

• Can only be separated used chemical means

​

Compounds

Fill in the Blanks

• Physical combinations of two or more substances that keep their own chemical properties

• Are only physically combined (mixed)

• Can be separated by physical means

​

Mixtures

Fill in the Blanks
