7/25/2023 0 Comments Metal rank as element![]() atomic number 3 atomic weight 6.941 melting point 180.5 C (356.9 F) boiling point 1,342 C (2,448 F) specific gravity 0.534 at 20. The metal itselfwhich is soft, white, and lustrousand several of its alloys and compounds are produced on an industrial scale. Metals in the fourth class are so unreactive they are essentially inert at room temperature. It also contains even less active metals such as copper, which only dissolves when treated with acids that can oxidize the metal. The lightest chemical element is Hydrogen. lithium (Li), chemical element of Group 1 (Ia) in the periodic table, the alkali metal group, lightest of the solid elements. Toxic metals, including heavy metals, are individual metals and metal compounds that negatively affect peoples health. The third class contains metals such as chromium, iron, tin, and lead, which react only with strong acids. ![]() Therefore the elemental metal will 'displace' the ionic metal and the two swap places. ![]()
