  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 orbit maximum # electrons 2 8 8 18 1 2 3 4

  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 9P 10N #e-= 9 #N = 10 draw the nucleus with protons & neutrons

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

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

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

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

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

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

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

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

  24. Bohr's Model of the Atom try these: hydrogen 1P 0N

  25. Bohr's Model of the Atom try these: 5P 6N boron

  26. Bohr's Model of the Atom try these: 12P 12N magnesium
