Definition of transition metal in English:

transition metal

(also transition element)

noun

Chemistry

Any of the set of metallic elements occupying a central block (Groups IVB–VIII, IB, and IIB, or 4–12) in the periodic table, e.g. iron, manganese, chromium, and copper. Chemically they show variable valency and a strong tendency to form coordination compounds, and many of their compounds are coloured.
Example sentencesExamples
- Iron and copper are the transition metal ions that are involved in the catalytic process of ROS generation.
- Manganese as a transition metal, one of the elements that occur in the middle of the periodic table in Rows 4, 5, and 6 between Groups 2 and 13.
- Tungsten is a transition metal, one of the elements that occupy the middle of the periodic table.
- Rhodium can be classified as a transition metal, a member of the platinum group of metals, and as a precious metal.
- We also observed qualitatively distinct behavior between the alkali-earth metal ions and the divalent transition metal ions in their action on the charged viruses.
