  1. write the conversion factors hat can be obtained form an equality such as 1m=100cm
    1m/100cm and 100cm/1m
  2. what equality is expressed by the conversion factor 1000g/1kg
    1000g=1kg
  3. use metric conversion
    (a)175cm meters=?
    (b) 5500mL Liters=?
    (c)0.0055kg grams=?
    • (a)1.75m
    • (b)5.5L
    • (c)5.5g
  4. equality
    =
  5. conversion factor
    /
  6. when setting up conversion factors, how do you know which item goes in the numerator and which goes in the denominator
    conversion factors must always be set up for unit cancellation
  7. has the smallest mass
    electron
  8. carries a positive charge
    proton
  9. found outside the nucleus
    electron
  10. electrically neutral
    neutron
  11. number of protons in an atom
    use atomic number
  12. number of neutrons in an atom
    • use both atomic number and mass number
    • mass number -atomic number =neutrons
  13. number of particles inthe nucleus
    use mass number
  14. number of electrons in a neutral atom
    use atomic number
  15. 1s shape?
    spherical
  16. 2p shape?
    dumbbell
  17. 5s shape?
    spherical
  18. similarity? 1s and 2s orbitals
    both spherical
  19. similarty? 3s and 3p subshell
    both part of the third energy level or shell
  20. similarity? 3p and 4p subshell
    both contain three p orbitals
  21. similarity? three 3p orbitals
    dumbbell shaped and belong in the third energy level or shell
  22. how many orbitals are in the 3d subshell?
    5
  23. how many subshells are in the energy level n=2 ?
    2(the 2s subshell and the 2p subshell)
  24. how many orbitals are in the 6p subshell?
    3
  25. how many orbitals are in the energy level n=3 ?
    9
  26. electrons in 2p orbital?
    2
  27. electrons in 3p subshell?
    6
