The density of osmium is slightly greater than that of iridium; the two are so similar (22.587 versus 22.562 g/cm 3 at 20 °C) that each was at one time considered to be the densest element. Only in the 1990s were measurements made accurately enough (by means of X-ray crystallography ) to be certain that osmium is the denser of the two.
So a ball made of a less dense material like (perhaps)_Osmium - which is still quite a bit denser than gold. Osmium is 22 times denser than water - so an osmium sphere would have about 4.7 times less surface area than a water balloon of the same mass. Since the drag force is proportional to the area, you'd have 4.7 times less drag force.
Osmium is denser by about 0.1%. See iridium#Characteristics which discusses the issue and provides some references. --Itub 16:50, 23 September 2008 (UTC) I updated the ranking and densities of osmium and iridium as per their respective articles. Unfortunately I suspect the degree of accuracy required to split these two elements means that the ...
Mercury is the heaviest liquid at room temperature. But the heaviest liquid irrespective of temperature is liquid osmium (a rare metal) at its melting point (3033°C/5491.4°F), with a density of 22.59 g·cm −3, 1.65 times as heavy as mercury. [4]
