Osmium is the densest of the elements. The most dense pure metal is osmium, Os, with a density of 22.61 g/cm3 (that's about twice the density of lead).
Other very dense metals are:
iridium, Ir, 22.56 g/cm3
platinum, Pt, 21.4 g/cm3
rhenium, Re, 21.0 g/cm3
neptunium, Np, 20.4 g/cm3
plutonium, Pu, 19.8 g/cm3
gold, Au, 19.3 g/cm3
tungsten, W, 19.3 g/cm3
Mercury, Hg, 13.53 g/cm3
Lead, Pb, which is usually considered pretty dense, is only 11.4 g/cm3! In case this isn't enough, lead will float on liquid mercury, which has a density of 13.5 g/cm3.
