# How much lead is there in the universe?

I know there is around 10^80 atoms in the observable universe, but is there any estimate the amount of lead in the universe (within a couple magnitudes of 10)?

Are you worried about being poisoned? – Ron Maimon Sep 24 '11 at 2:08
No, actually, I am wondering whether the amount of lead is merely small (less than 1 / 10^3) or vanishingly rare (less than 1 / 10^60) – donnyton Sep 24 '11 at 2:16
The estimated fraction of lead atoms in the universe is $6\cdot10^{-11}$. – mmc Sep 24 '11 at 2:59
@mmc: why not post as an answer? Also: does this belong on Astronomy? – David Zaslavsky Sep 24 '11 at 3:45
@mmc: fair enough, I understand the reluctance to post a very short answer... but I think that if you have an answer, as long as it really does answer the question, even if it is very short, it's better to post it as an answer than as a comment. – David Zaslavsky Sep 24 '11 at 4:15
