I've been pitting my wits on the 'Sporcle Periodic Table' free site, where you have to type in all the 118 elements in 15 minutes. I'd got all the unun- ones learned, then they gave them new names, as you say Freddy. I last studied Chemistry fifty years ago, only to 'O' Level. but I can now rattle the 118 off in about 5 minutes, including nihonium, moscovium etc.
I also like the ASAP team on Youtube, who sing a lovely song with all the elements in (but not the new names sadly!) to the Can-Can tune!
