Memorizing and Recognizing Molecular Shapes

In Topic 2E of the textbook, there are 12 molecular shapes listed. Are those all the ones we need to be able to recognize or are there more or less? Furthermore, do we need to know the bond angles that correspond with those shapes?

Finding electron configurations

How do you find the electron configuration using noble gases? I understand that you need to list the noble gas from the previous period but how do you count afterwards? Say for example we are trying to find the electron configuration of Gallium(Ga) as well as the electron configuration of Niobium(Nb)

Re: Photons

If a photon doesn't have enough energy(work function) to eject a photon then nothing will happen. The photon's energy will simply be absorbed by the electron but with no results or consequences.

Re: Photons

Yes, it is possible for a photon to not have enough energy. If it does not then it won't be able to eject an electron. Like in lecture on Week 2, a photon packet overall does not need to have intense energy, but each photon itself must have enough intensity.
