Re: Studying for tests/midterm

I would also consider looking up videos on youtube or the ones that Dr. Lavelle has posted on the class website since I found those to be really helpful.

Re: Difference in energy between s-, p-, d-, f- orbitals in the same shell

I think there is more shielding in the p- orbitals and up. Electrons in the s- orbital cause the shielding to the other orbitals. Since they are closer to the nucleus, they block some of the pull to the other electrons, so the electrons in the other orbitals are as a result at a higher energy level.

Re: Energy Levels

I believe that part of the reason there is such a big gap initially is that the electrons have a stronger pull to the nucleus because it is so close in n=1, so it requires more energy to remove the electron. As the n increases, there is less pull along with greater shielding, so it requires less ene...
