oxidation state - the degree of oxidation of an atom or ion or molecule; for simple atoms or ions the oxidation number is equal to the ionic charge; "the oxidation number of hydrogen is +1 and of oxygen is -2" oxidation number number - a concept of quantity involving zero and units; ...
Unambiguous determination of metal atom oxidation state in an intact metalloprotein is achieved by matching experimental (electrospray ionization 9.4 tesla Fourier transform ion cyclotron resonance) and theoretical isotopic abundance mass distributions for one or more holoprotein charge states. The iron atom...
Related to oxidation:oxidation number,oxidation state ox·i·da·tion (ŏk′sĭ-dā′shən) n. 1.The combination of a substance with oxygen. 2.A reaction in which the atoms of an element lose electrons and the valence of the element is correspondingly increased. ...
The catalytic activity of metals supported on oxides depends on their charge and oxidation state. Yet, the determination of the degree of charge transfer at the interface remains elusive. Here, by combining density functional theory and first-principles
Knowledge of the oxidation state of metal centres in compounds and materials helps in the understanding of their chemical bonding and properties. Chemists have developed theories to predict oxidation states based on electron-counting rules, but these can fail to describe oxidation states in extended cr...
Oxygen-atomtransfer Carbonreacts withmercury(II) oxide (acompoundin which mercury has a bonding capacity expressed as +2;see belowOxidation-state change) to producecarbon dioxideand mercurymetal. This reaction can be written in equation form: ...
Blocking the metal with molecular CO prevents this catalytic action. Even if the surface is saturated with oxygen, with the thickness of the oxidised layer being 15 , Co metal is still present in the topmost layer. The unability of the metallic component at the CoSi surface to establish metal...
The oxidation state of a transition metal in a crystal lattice is conventionally viewed as reflecting physical ionization: electrons have been transferred to or from the atom, leaving a point-like charged entity (ion). Such a picture is still sometimes i
Blocking the metal with molecular CO prevents this catalytic action. Even if the surface is saturated with oxygen, with the thickness of the oxidised layer being 15 , Co metal is still present in the topmost layer. The unability of the metallic component at the CoSi surface to establish metal...
A chemical laser which operates by formation of metal or carbon atoms and reaction of such atoms with a gaseous oxidizer in an optical resonant cavity. The lasing species are diatomic or polyatomic in
