Lecture #16, Friday October 30th

After our discussion of electron configurations, we can assign a set of four quantum numbers to each electron in an atom. Chemists are interested in analyzing how electrons interact, so labeling them is important. Be sure to draw out the orbital block diagram to interpret the quantum numbers for each electron.

Each electron has a set of four quantum numbers and we discussed each of them and carried out an example by listing the set of four quantum numbers for the valence electrons in a nitrogen atom.

I ended class by discussing radial and angular nodes and talking about probability density functions. Be sure to read the "A closer look" box on page 230-231 in the textbook.
