  1. Head a paper for class notes • Record all drawings and data charts in notes • Record any writing that is in yellow • You do not need to record all of the examples at the very end but you should check your understanding using them

  2. INSIDE THE ATOM

  3. NUCLEUS

  4. THE NUCLEUS IS . THE CENTER .OF THE ATOM

  5. TODAY’S MODEL SAYS THE NUCLEUS CONTAINS TWO KINDS OF SUBATOMIC PARTICLES...

  6. SUBATOMIC PARTICLES ARE THE TINY PARTICLES THAT MAKE UP THE ATOM

  7. PROTON +

  8. PROTON POSITIVE ONE A.M.U. IN THE NUCLEUS

  9. NEUTRON +

  10. NEUTRON NEUTRAL ONE A.M.U. IN THE NUCLEUS

  11. - ELECTRON

  12. ELECTRON NEGATIVE 1/2000 A.M.U. ORBITS AROUND NUCLEUS

  13. 3 MAIN SUBATOMIC PARTICLES PROTON POSITIVE ONE A.M.U. IN THE NUCLEUS IN THE NUCLEUS NEUTRON NEUTRAL ONE A.M.U. ORBITS AROUND NUCLEUS 1/2000 A.M.U. ELECTRON NEGATIVE

  14. HYDROGEN 1 1 H

  15. HYDROGEN 1 1 ATOMIC NUMBER H

  16. THE ATOMIC NUMBER IS EQUAL TO THE NUMBER OF PROTONS AN ATOM HAS.THE NUMBER OF PROTONS IS WHAT DETERMINES WHAT ELEMENT IT IS

  17. HYDROGEN 1 1 MASS NUMBER H

  18. THE MASS NUMBER EQUALS THE NUMBER OF PROTONS PLUS THE NUMBER OF NEUTRONSSO# OF NEUTRONS =MASS # - ATOMIC #

  19. ATOMS DO NOT HAVE AN OVERALL CHARGE SO THE NUMBER OF ELECTRONS… IS THE SAME AS THE NUMBER OF PROTONS (OR THE ATOMIC #)

  20. HYDROGEN 1 HOW MANY: PROTONS? 1 1 H ELECTRONS? 1 NEUTRONS? 0

  21. - HYDROGEN +

  22. LITHIUM 7 HOW MANY: PROTONS? 3 3 Li ELECTRONS? 3 NEUTRONS? 4

  23. ARSENIC 75 HOW MANY: PROTONS? 33 33 As NEUTRONS? 42 ELECTRONS? 33

  24. Bromine 80 HOW MANY: PROTONS? 35 35 Br ELECTRONS? 35 NEUTRONS? 45

  25. INDIUM 115 HOW MANY : # NEGATIVE CHARGES ? 49 49 In # NEUTRAL CHARGES? 66 WHAT ELSE ? # PROTONS 49

  26. FLUORINE 19 WHAT IS: ATOMIC # ? 9 9 F MASS NUMBER? 19 # OF NEGATIVE CHARGES? 9
