You know the knowledge imparted by your high school chemistry teacher has disintegrated when you score, as I did, a mere 33 out of 118 on the Periodic Table. It’s one thing to miss not-named-until-after-graduation elements like dubnium, which I learned as unnilpentium. I’m even willing to forgive myself for not remembering not-so-everyday elements like scandium or ruthenium. But how embarrassed am I to miss so many obvious elements, like sulfur, lead, iodine, and nickel.
