I wish I could! I can remember the top couple of lines and used to remember more but I’ve never managed to memorise it all. There is the periodic table song to try and help you remember: https://www.youtube.com/watch?v=zUDDiWtFtEM
We had to learn the whole periodic table in the first year of university. I think I’ve forgotten quite a lot of it now but I love it when a periodic table question comes up on pointless – I usually manage to remember a pointless answer!
