Which is the lightest (least dense) metal?
Period 2 element two make up all natural occurrence of lithium on Earth, although further isotopes have been synthesized. In ionic compounds, lithium loses an electron to become positively charged, forming the cation Li. Lithium is the first alkali metal in the periodic table, and the first metal of any kind in the periodic table. At standard temperature and pressure, lithium is a soft, silver-white, highly reactive metal. With a density of 0.564 g·cm, lithium is the lightest metal and the least dense solid element. Lithium is one of the few elements synthesized in the Big Bang, making it a primordial element. Lithium
Dense Inert Metal Explosive bombs. Gilbert and Fosse made the same accusations during the ongoing 2014 Gaza conflict. Dense Inert Metal Explosive Dense Inert Metal Explosive (DIME) is an experimental type of explosive that has a relatively small but effective blast radius. It is manufactured by producing a homogeneous mixture of an explosive material (such as phlegmatized HMX or RDX) and small particles of a chemically inert material such as tungsten. It is intended to limit the distance at which the explosion causes damage, to avoid collateral damage in warfare. The phrase "inert metal" refers to a metal that is not chemically active and
