Uranium (U) density: 19,05 g/cm3
Silica (SiO2) density: 2,634 g/cm3
Iron is heavier because iron is a metal and metals are heavier but silica is not a metal so silica is lighter than iron.
Yes, uranium is more dense (heavier) than lead.
No, iron is heavier than silica. Iron has a density of about 7.87 g/cm^3, whereas silica (silicon dioxide) has a density of about 2.65 g/cm^3.
Uranium, U is.
The density of water is 1 g/cm3 and the density of uranium is 19,06 g/cm3; the ratio is approx. 19.
Uranium is not lighter but heavier than many of the other elements; the density of uranium is 19,05 g/cm3 and the atomic weight is 238,02891.

There are as many as 17 elements which are denser (and therefore heavier) than gold. Most of them are transuranic elements, almost all of which have a half-life measured in fractions of a second.The densest of the non-transuranic elements is osmium, which is about 17% heavier than gold. It is closely followed by iridium, then platinum and rhenium.
Atoms heavier than iron are typically produced through processes like nuclear fusion in supernovae or in laboratories. Some examples include atoms like uranium, plutonium, and lead, which have more protons and neutrons in their nuclei compared to iron.
