Phosphorus pentoxide - Wikipedia

Structure. Phosphorus pentoxide crystallizes in at least four forms or polymorphs.The most familiar one, a metastable form (shown in the figure), comprises molecules of P 4 O 10.Weak van der Waals forces hold these molecules together in a hexagonal lattice (However, in spite of the high symmetry of the molecules, the crystal packing is not a close packing).

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– (molecular) ion. 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 oxidized by the ...

Lead - Wikipedia

Lead is a chemical element with the 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 also has a relatively low melting point.When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element ...

Lithium oxide - Wikipedia

Lithium oxide is produced by thermal decomposition of lithium peroxide at 300-400°C. Lithium oxide forms along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen: 4Li + O 2 → 2 Li 2 O. Pure Li 2 O can be produced by the thermal decomposition of lithium peroxide, Li 2 O 2, at 450 °C. 2 Li ...
