What's the densest element?

[Mark R]

Well, what is it? Room temperature, stable allotrope.

That's not stable. Bi-209 has the highest atomic weight but I'm not sure if it's also the most dense. Pb-208 is probably the most common answer to the question.

For some reason I remember reading that tungsten was the one, but its mean years since I've taken a chemistry class

tungsten is very dense, but not the densest according to this MIT table

Unobtainium (see The Core)

That is at about 50degree F ...not room temp

A platinum family metal, iridium, is white, resembling platinum, but with a slight yellowish cast. Due to its extreme hardness and brittle properties, iridium is difficult to machine, form, or work. Iridium is the most corrosion-resistant metal known
Iridiuim can not be attacked by any acids or by aqua regia, but it can be attacked by molten salts, such as NaCl and NaCN. The specific gravity of this element is only slightly lower than osmium, which is generally considered to be the heaviest element known. However, calculations of density from the space lattice may produce more reliable data for these elements than actual measurements and give a density of 22650 for iridium versus 22661 for osmium. Definitive selection between the two is therefore not possible at this time. It's just too close to call.

Well if we are nitpicking, 300 K = 26.9°C = 80.3°F.
