Oxidation states are typically represented by integers which may be positive, zero, or negative. In some cases, the average oxidation state of an element is a fraction, such as 8 / 3 for iron in magnetite Fe 3 O 4 . The highest known oxidation state is reported to be +9, displayed by iridium in the tetroxoiridium(IX) cation (IrO + 4). [1]
Each string oxidation-state-number values an oxidation-state-number eg "+3," starts with a space or a newline, followed by; a math minus sign (not a dash) OR; a plus OR; nothing; followed by number, followed by comma (every entry including the last one), a referenced-oxidation-state-number is an oxidation-state-number followed by a <ref ...
In the first six periods this does not make a difference to the relative order, but in the seventh period it does, so the seventh-period elements have been excluded. (In any case, the typical oxidation states for the most accessible seventh-period elements thorium and uranium are too high to allow a direct comparison.) [11]
(depending on the oxidation state, an acidic, basic, or amphoteric oxide) -- Cr, Mn comment=rarely non-0, weakly acidic (rarely more than 0; a weakly acidic oxide ) -- Xe
Other predicted oxidation states include +2, +4, and +6; +4 is expected to be the most usual oxidation state of unbihexium. [16] The superactinides from unbipentium (element 125) to unbiennium (element 129) are predicted to exhibit a +6 oxidation state and form hexafluorides, though 125F 6 and 126F 6 are predicted to be relatively weakly bound ...
Mantle oxidation state changes because of the existence of polyvalent elements (elements with more than one valence state, e.g. Fe, Cr, V, Ti, Ce, Eu, C and others). Among them, Fe is the most abundant (≈8 wt% of the mantle [2]) and its oxidation state largely reflects the oxidation state of mantle.
