Lecture on Electronic Structure

We've started a new unit, and it has been going pretty well. At first, the unit seemed a bit confusing, but it all began to make sense gradually. The first lesson of the unit was on wavelengths of light. We learned the formula for the speed of light (C= frequency x wavelength) and for energy (E= Planck's constant x frequency). These two formulas were easy to understand as problems associated with the lesson are pretty basic plug-and-chug. Yesterday, we learned about the electron configuration of elements. This lesson was chockful of vocab and steps to memorize. It was definitely a bit confusing and time-consuming at first to figure out each element's different electron structure and diagram and to memorize all the little rules for different types of elements. However, I soon began to understand it, and I even think it's a bit fun (Something I have NEVER said about chemistry, so that's saying a lot!).
