Presentation Transcript

  1. Matter and Atoms 4-1

  2. What is Matter? • Matter – a term used to describe anything that has mass and takes up space • Not matter • Light • Heat • Energy

  3. Early Ideas • Democritus • Universe made of empty space and tiny bits of stuff • Atom – Greek word meaning “can not divide”

  4. Atom • Atom – a small particle that makes up most types of matter

  5. Conservation of Matter • 2,000 years pass • Lavoiser – showed that no change in mass during chemical reactions • Example – log burning

  6. Proust • Proust – matter is made of small particles that behave in ways that can be predicted and measured

  7. Dalton’s Models of an Atom • John Dalton – 1st model of an atom • All of the atoms in something are identical • Atoms of different elements are different from each other

  8. Size of an Atom • 1980’s – electron microscopes • Allowed Scientist to see an atom

  9. Inside an Atom • Nucleus – center of an atom • Contains protons and neutrons • Proton – particle with a positive charge (+) • Neutron – particle with no charge (0) • Most of mass

  10. Inside an Atom • Electrons – particle inside an atom with a negative charge • Equal number of protons and electrons • Located in electron cloud
