  1. Are atoms with unpaired electrons unreactive?
    • No, electrons that are unpaired are highly reactive.

  2. Where are electrons most likely to be found?
    • Sub-Shells/orbitals named s,p,d,f orbital

  3. How many electrons can each orbital contain?
    • Maximum of 2

  4. How are the number of main shells determined?
    • Distance of the main shell from the nucleus (volume)

  5. How is it best to find the electron configuration of Ions?
    • Find out the electron configuration of the uncharged atom, then add or subtract the number of electrons gained or lost

  6. Which one of these atoms is in the excited state?
    1s2, 2s2, 2p5, 3s1
    1s2, 2s2, 2p6
    • 1s2, 2s2, 2p6

  7. The .... levels of ..... and .... are quite similar. A consequence of this is that ................ will lose ... electrons before losing 3d
    • The energy levels of 4s and 3d are quite similar. A consequence of this is that transition metals will lose 4s electrons before losing 3d
