    Lead oxides are a group of inorganic compounds with formulas including lead (Pb) and oxygen (O).. Common lead oxides include: Lead(II) oxide, PbO, litharge (red), massicot (yellow)

  4. Lead(II) oxide - Wikipedia

    en.wikipedia.org/wiki/Lead(II)_oxide

    Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb O.PbO occurs in two polymorphs: litharge having a tetragonal crystal structure, and massicot having an orthorhombic crystal structure.

  5. Lead dioxide - Wikipedia

    Crystal structure of α-PbO 2 Crystal structure of β-PbO 2. Lead dioxide has two major polymorphs, alpha and beta, which occur naturally as rare minerals scrutinyite and plattnerite, respectively. Whereas the beta form had been identified in 1845, [3] α-PbO 2 was first identified in 1946 and found as a naturally occurring mineral 1988. [4]

  6. Lead (II) phosphate - Wikipedia

    Lead(II) phosphate is an ionic compound with chemical formula Pb 3 (P O 4) 2.Lead(II) phosphate is a long-lived electronically neutral reagent chemical. [2] Despite limited tests on humans, it has been identified as a carcinogen based on tests on animals conducted by the EPA. [3]

  7. Minium (mineral) - Wikipedia

    en.wikipedia.org/wiki/Minium_(mineral)

    Minium is the naturally occurring form of lead tetroxide, Pb 2+ 2 Pb 4+ O 4 also known as red lead. Minium is a light-to-vivid red and may have brown-to-yellow tints. It typically occurs in scaly-to-earthy masses.

  8. Polyoxometalate - Wikipedia

    en.wikipedia.org/wiki/Polyoxometalate

    The phosphotungstate anion, an example of a polyoxometalate. In chemistry, a polyoxometalate (abbreviated POM) is a polyatomic ion, usually an anion, that consists of three or more transition metal oxyanions linked together by shared oxygen atoms to form closed 3-dimensional frameworks.

  9. Tetraoxygen - Wikipedia

    en.wikipedia.org/wiki/Tetraoxygen

    Tetraoxygen was first predicted in 1924 by Gilbert N. Lewis, who proposed it as an explanation for the failure of liquid oxygen to obey Curie's law. [1] Though not entirely inaccurate, computer simulations indicate that although there are no stable O 4 molecules in liquid oxygen, O 2 molecules do tend to associate in pairs with antiparallel spins, forming transient O 4 units.
