The Perodic Table is quit logical in it's configuation. It is amazing how the elements can be arranged by the number of protons, and how valance electrons fit into the arrangement of the table. It has been years since I have taken a chemistry( actually the last chemistry class I had taken was high school) I was not sure how I was going to like chemistry. There has been alot of change in chemistry, and I am having fun learning all the new chemistry stuff. One of the new things I really like working out are Lewis Structures , I find these problems fun and challenging, I like working out these kinds of problems.
