This lecture was confusing at first, but got easier as we went along. We first had to color in the s,p,d, and f sub levels on our periodic table. Then we used the periodic
table to classify the elements based on the number of electrons they
had. In addition, we had to write the electron configuration of elements by
using the valence electrons, and using the classifications on the
periodic table. We also used the elements that accept electrons from
lower levels in order to write their configurations correctly. During this lesson, we also looked at the 6 transition elements (Cr, Cu, Mo, Ag, W, Au) that do not always follow the rules that the other elements do.
