Which one is lightest mercury or Aluminium?

Density determinesthe heaviness, or lightness of a given material. Among the four elements given above, Aluminium has the least density of 2.7 gms / cm3 , and hence Al is the lightest among the 4 metals : Al, Cu, Hg, and Pb.

Which of the following is lightest one gram of mercury?

Atomic weight of Ig of mercury is g. Atomic weight of 1 mol of mercury is g. Atomic weight of 1 atom of mercury is g. ∴ lg atom of mercury is lightest.

Which is heavier copper or mercury?

Copper is more dense than mercury.

Which metal is most lightest?

The lightest or least dense metal that is a pure element is lithium, which has a density of 0.534 g/cm3. This makes lithium nearly half as dense as water, so if lithium was not so reactive, a chunk of the metal would float on water. Two other metallic elements are less dense than water.
