  1. Bohr's Model of the Atom

  2. Bohr's Model of the Atom Niels Bohr (1913):

  3. Bohr's Model of the Atom Niels Bohr (1913): -studied the light produced when atoms were excited by heat or electricity

  4. Bohr's Model of the Atom Niels Bohr (1913): -studied the light produced when atoms were excited by heat or electricity

  5. Bohr's Model of the Atom Niels Bohr (1913): -studied the light produced when atoms were excited by heat or electricity Rutherford's model couldn't explain why unique colours were obtained by atoms of different elements

  6. Bohr's Model of the Atom Niels Bohr (1913): -studied the light produced when atoms were excited by heat or electricity Rutherford's model couldn't explain why unique colours were obtained by atoms of different elements Bohr proposed that electrons are in orbits & when excited jump to a higher orbit. When they fall back to the original they give off light

  7. Bohr's Model of the Atom Bohr's model: -electrons orbit the nucleus like planets orbit the sun

  8. Bohr's Model of the Atom Bohr's model: -electrons orbit the nucleus like planets orbit the sun -each orbit can hold a specific maximum number of electrons

  9. Bohr's Model of the Atom Bohr's model: -electrons orbit the nucleus like planets orbit the sun -each orbit can hold a specific maximum number of electrons

  10. Bohr's Model of the Atom Bohr's model: -electrons orbit the nucleus like planets orbit the sun -each orbit can hold a specific maximum number of electrons -electrons fill orbits closest to the nucleus first.

  11. Bohr's Model of the Atom e.g. fluorine: #P = #e- = #N =

  12. Bohr's Model of the Atom e.g. fluorine: #P = atomic # = 9 #e- = #N =

  13. Bohr's Model of the Atom e.g. fluorine: #P = 9 #e- = # P = 9 #N =

  14. Bohr's Model of the Atom e.g. fluorine: #P = 9 #e- = 9 #N = atomic mass - # P = 10

  15. Bohr's Model of the Atom e.g. fluorine: #P = 9 #e- = 9 #N = 10 draw the nucleus with protons & neutrons 9P 10N

  16. Bohr's Model of the Atom e.g. fluorine: #P = 9 #e- = 9 #N = 10 how many electrons can fit in the first orbit? 9P 10N

  17. Bohr's Model of the Atom e.g. fluorine: #P = 9 #e- = 9 #N = 10 how many electrons can fit in the first orbit? 2 9P 10N

  18. Bohr's Model of the Atom e.g. fluorine: #P = 9 #e- = 9 #N = 10 how many electrons are left? 9P 10N

  19. Bohr's Model of the Atom e.g. fluorine: #P = 9 #e- = 9 #N = 10 how many electrons are left? 7 9P 10N

  20. Bohr's Model of the Atom e.g. fluorine: #P = 9 #e- = 9 #N = 10 how many electrons are left? 7 how many electrons fit in the second orbit? 9P 10N

  21. Bohr's Model of the Atom e.g. fluorine: #P = 9 #e- = 9 #N = 10 how many electrons are left? 7 how many electrons fit in the second orbit? 8 9P 10N

  22. Bohr's Model of the Atom e.g. fluorine: #P = 9 #e- = 9 #N = 10 9P 10N

  23. Bohr's Model of the Atom try these: hydrogen boron magnesium
