0 any of a group of metal chemical elements including copper and gold that show more than one valency (= the number of hydrogen atoms that can combine with one of its atoms to form a compound)
As a result, these soils contain high concentrations of oxidized transition metal minerals, particularly chromium and manganese, as well as perchlorate.
A difficulty is that there are not many transition metal systems for which accurate experimental binding energies are known.
Therefore, it has been most successfully applied to organic radicals and half-integer spin transition metal ions.
Site-specific labeling of proteins with cyclen-bound transition metal ions.
Electronic structure analysis of electron-transfer matrix elements for transition metal redox pairs.
It is also not conceivable why hydrogen peroxide (of hypothetically biological origin) should release oxygen when humidified, without mentioning the presence of any transition metal salt catalysts.
Enantioselective reductions of ketones may be accomplished through the use of catalytic amounts of chiral transition metal complexes.
It is typically the second most abundant transition metal in organisms after iron and it is the only metal which appears in all enzyme classes.
