Elements in a high oxidation state have an oxidation state higher than +4, and also, elements in a high valence state ( hypervalent elements) have a valence higher than 4. See more In chemistry, the valence (US spelling) or valency (British spelling) of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules. See more Valence is defined by the IUPAC as: The maximum number of univalent atoms (originally hydrogen or chlorine atoms) that may combine with an atom of the element under … See more For elements in the main groups of the periodic table, the valence can vary between 1 and 7. Many elements have a common valence related to their position in the periodic table, and nowadays this is rationalised by the See more Frankland took the view that the valence (he used the term "atomicity") of an element was a single value that corresponded to the maximum value observed.
