Presentation Transcript

  1. Structure of Matter Analyze what makes up matter Compare the different models of an atom.

  2. Structure of Matter mass Define matter anything that has _________ and takes up space

  3. Structure of Matter What is matter? • air is matter • water is matter • most of the things you see, taste, smell, and touch are made of matter

  4. Structure of Matter What isn’t matter? • light • heat • thoughts, feelings, ideas these things have no mass, nor do they take up space

  5. Structure of Matter What makes up matter? atoms

  6. Structure of Matter Define atom a particle that makes up most types of ___________ matter

  7. Structure of Matter created destroyed Can matter be made or destroyed? matter is not _________ nor ___________, it just changes into a different form this is the law of conservation of matter

  8. Structure of Matter Before Lavoisier, people used to think _________ could appear and disappear. matter

  9. Structure of Matter What was Dalton’s model of an atom? the atomic theory of matter: each type of matter was made of only _________ of atom one kind

  10. Structure of Matter How small is an atom? 1 million lined up in a row would be as thick as a human hair (too small to be seen by a classroom microscope)

  11. Structure of Matter What is an electron? invisible particles of an atom with negative charges

  12. Structure of Matter What was Thomson’s model of an atom? Thomson thought an atom was a ball of ______________ with negatively charged electrons in it positive charges

  13. Structure of Matter nucleus What was Rutherford’s model of an atom? Rutherford’s model included a ________ with protons inside and electrons around the nucleus

  14. Structure of Matter Define nucleus positively charged, central part of an atom

  15. Structure of Matter positively Define proton ___________ charged particles in the nucleus of an atom

  16. Structure of Matter How was the neutron discovered? James Chadwick, a student of Rutherford, discovered neutral particles that gave the nucleus more mass

  17. Structure of Matter Define neutron neutral particle in the nucleus of an atom

  18. Structure of Matter What was Bohr’s model of an atom? Bohr’s model indicated that electrons traveled in paths around the nucleus (lowest energy levels closest to the nucleus)

  19. Structure of Matter Modern Atomic Model Electrons travel in an electron cloud rather than in paths
