When we talk about how heavy a metal is, we're really talking about how dense it is. Density is a measure of how tightly packed matter is. The density of a material is mass per unit volume. Density is measured in kilograms per cubic meter (kg\/m3) or grams per cubic cm (g\/cm3).<\/p>\n
He osmium<\/strong> and the iridium<\/strong> are the densest metals in the world<\/strong>but relative atomic mass is another way to measure \"weight.\" The heaviest metals<\/strong> in terms of relative atomic mass they are the plutonium<\/strong> and the uranium<\/strong>.<\/p>\n Osmium and iridium are the densest metals.<\/strong>In other words, its atoms clump together more tightly in solid form than other metals. With a density of 22.6 g\/cm3 and 22.4 g\/cm3 respectively, osmium and iridium are approximately twice as dense as lead, which has a density of 11.3 g\/cm3. Osmium and iridium were discovered by the chemist English Smithson Tennant<\/strong> in 1803.<\/p>\n The heaviest natural element is plutonium<\/strong> (atomic number 94, relative atomic mass 244.0). Other heavy metals in terms of relative atomic mass are uranium<\/strong> (atomic number 92, relative atomic mass 238.0289), radium (atomic number 88, relative atomic mass 226.0254), and radon (atomic number 86, relative atomic mass 222.0).<\/p>\n References:<\/strong><\/p>\n https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3113373\/<\/a>The densest metals<\/h2>\n
