WebMay 8, 2024 · Silver and copper are the two best conductors of heat and electricity. Lead is the poorest conductor of heat. Bismuth, mercury and iron are also poor conductors Density: Metals have high density and are very heavy. Iridium and osmium have the highest densities where as lithium has the lowest density. WebMar 2, 2024 · This is the case in the most conductive metals, such as silver, gold, and copper. Each has a single valence electron that moves with little resistance and causes a strong repelling reaction. Semiconductor metals (or metalloids) have a higher number of valence electrons (usually four or more). fishing techniques for beginners
