Week 2-Readings/Atomic Properties Menu

This site was helpful. A lot of it was overlap from our notes, but it was great to read all this info again to understand orbitals. I did imagine since I first took chemistry in high school until now, that the electrons in these orbitals followed a certain pathway just like "orbits". I didn't realize with the Heisenberg Uncertainty Principal, that we can't know where the electron will go next. I also like Hund's rule, which states that electrons will fill orbitals singly in the same energy level. This helps to make the atom more stable. How does it know to do that? So crazy...Knowing the number of protons is the same as the number of electrons was helpful in learning to write notation for the atoms' orbitals and electrons.
