Which natural element has the highest density?

I've been studying in the periodic table and it has really helped my game. I am still studying Greek Mythology too and that CV is helping alot . my next subject is MATH A-Z. I've been in the knowledge era for awhile now!! good luck to you, no matter what level you are on. I am on 946 and the questions are just getting harder and harder. i will never give up but it is disheartening when you lose a life or more!!
