    Wait Tiff when you say match element symbols with names does that mean we have to memorize the elements and their symbols? Aren’t we going to have a periodic table?

      yes, you’ll have a periodic table so you don’t need to memorize it! i just mean that you should be able to find that “C” is for carbon, not chlorine, and gold is not “Go”
