I’ve memorised the stable isotopes (including extremely long lived one) of all the elements up to arsenic. It gets more complicated and harder to remember as they get heavier.

Memorized up to plutonium, I don’t see the point of memorizing the larger synthetic elements. But I still need to memorize the symbols for each element and the atomic mass. I also want to memorize the most common isotopes of each element.
