Super Heavy New Element

93 through 113 have all been created. 112 was just certified, 113 hasn't yet been (only 8 atoms have been reported created).

93, Neptunium, is entirely man made but has some industrial uses and the stablest isotope has a half life of a couple million years. You've probably heard of 94 - plutonium.

And it isn't so much that these high weight atoms don't occur in nature as that they don't survive long enough to be observed.
