  • Oxide Wikipedia

    An oxide / ˈ ɒ k s aɪ d / is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O 2 atom. Metal oxides thus typically contain an anion of oxygen in the oxidation state of 2. Most of the Earth's crust consists of solid oxides, the result of elements being

    Lead is a chemical element with symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and has a relatively low melting point.When freshly cut, lead is bluish-white; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic
