Oxidation Number

Science / Chemistry / Oxidation Number: A convention for representing a charge of an atom embedded within a compound, if the compound were purely ionic. For example, H2O is a covalent compound; if it were ionic, the hydrogens would be H+ (o MORE


Science / Chemistry / Autoxidation: Oxidation caused by exposure to air. Rust is an example of autoxidation. Autoxidation makes ether taken from half-filled bottles very dangerous, because air oxidizes ether to highly explosive organic MORE

Oxidation Half Reaction

Science / Chemistry / Oxidation Half Reaction: That part of a redox reaction that involves loss of electrons. In the oxidation half reaction, the oxidation number of one or more atoms within the reactants is increased. MORE

Oxidation Product

Entertainment / Photography / Oxidation Product: Is the chemical produced by a color developer during the conversion of exposed silver halides to black metallic silver. MORE

Phosphorus (P)

Science / Periodic Table of Elements / Phosphorus (P): Atomic number: 15, Atomic mass: 30,9738 g.mol -1, Oxidation states: ± 3, 4, 5, Electronegativity: 2,1, Density: 1,82 g/ml at 20°C, Melting point: 44,2 °C, Boiling point: 280 °C, Vanderwaals radius MORE


Science / Chemistry / Corrosion: Corrosion is a reaction that involves action of an oxidizing agent on a metal. The oxidizing agent is often oxygen dissolved in water. See How Iron Rusts for examples. MORE
