The Atomprobe

  1. 1. ATOMIC STRUCTURE S.MORRIS 2006 This Powerpoint is hosted on www.worldofteaching.com Please visit for 100’s more free powerpoints
  2. 6. When matter and antimatter particles collide they annihilate into energy,  radiation
  3. 9. HELIUM ATOM + N N + - - proton electron neutron Shell What do these particles consist of?
  4. 14. Quarks are one type of matter particle. Most of the matter we see around us is made from protons and neutrons, which are composed of quarks. More info on quarks: http://www.particleadventure.org/frameless/quarks.html
  5. 24. Isotopes <ul><li>Atoms of the same element with different numbers of neutrons. </li></ul><ul><li>Isotope symbol: </li></ul>“ Carbon-12” Mass # Atomic #
  6. 25. A. Chemical Symbols <ul><li>Capitals matter! </li></ul><ul><li>Element symbols contain ONE capital letter followed by lowercase letter(s) if necessary. </li></ul>Co vs. CO Metal that forms bright blue solid compounds. Poisonous gas.
  7. 26. The atom is comprised of three major particles—protons, neutrons and electrons. There are four forces (Electromagnetic, Strong, Weak, and Gravity) that are responsible for the behavior of the particles and thus keep the atom together .
  8. 38. Rutherford’s gold foil experiment <ul><li>http://www.shsu.edu/%7Echm_tgc/sounds/pushmovies/l2ruther.gif - source of animation </li></ul>
  9. 40. Bohr Model Diagrams <ul><li>Simplified energy levels using Bohr’s idea of circular orbits. </li></ul>e- e- Maximum e - Level 1 2e - Level 2 8e - Level 3 18e - Level 4 32e - Lithium Atomic #: 3 Mass: 7 # of p: 3 # of e: 3 # of n: 4 e- p p n n n n p Can replace with: 3p 4n
