What is least dense metal?
Mercury or â??quicksilverâ?? is considered the least conductive metal. It's dense, toxic and exists in liquid form. Its use has declined over the years due to health and environmental concerns. Held at room temperature, it appears as a thick, silvery liquid , highly dense with low heat conductivity. Its electrical conductivity allows it to easily form amalgams with silver and gold.
Mercury is the only metal that is liquid at room temperature. The others are all solid. It is also a very dense metal (twice as dense as iron) and it can be used to dissolve gold. Many mercury compounds are highly toxic, especially methyl mercury. Mercury sulfide is the least water-soluble compound known to science.
It is a soft, silver-white metal belonging to the alkali metal group of chemical elements. Lithium is a chemical element with symbol Li and atomic number 3. It is the lightest metal and the least dense solid element. Lithium is highly reactive and flammable. For this reason, it is typically stored in mineral oil.
One unusual property is the very low density of lithium, at 0.534 g/cm3. Usually metals have high densities but lithium does not, which can be attributed to the fact that lithium is a group I metal, and in fact, the first group I metal. This means that lithium metal will actually float on water and on any hydrocarbon oil. It is less dense than any liquid element and also the least dense of elements that…
