Before long you'll assimilate a lot more elements into your long-term memory and what gets stored there will make some logical sense.įor example, all of the noble gas elements (under He) are much more similar than different. If you know these elements, then you've got a framework on which to build a memory of the other elements in the group as you study chemistry. These are the elements at the top of each column (group), and they are generally representative of the other elements in the group. I ask my students to memorize the first ten elements of the table: H, He, Li, Be, B, C, N, O, F and Ne. Your chemistry teacher might disagree with me, so be careful here, but my view is this:
