noun
- 1. 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.

Oct 26, 2024 · transition metal, any of various chemical elements that have valence electrons—i.e., electrons that can participate in the formation of chemical bonds—in two shells instead of only one. While the term transition has no particular chemical significance, it is a convenient name by which to distinguish the similarity of the atomic structures ...
Oct 5, 2024 · Transition Metal Definition. The most common definition of a transition metal is the one accepted by the IUPAC. A transition metal is an element with a partially-filled d subshell or the capacity to produce cations with an incomplete d subshell. Other people consider the transition metals to include any d -block element on the periodic table.
In chemistry, a transition metal (or transition element) is a chemical element in the d-block of the periodic table (groups 3 to 12), though the elements of group 12 (and less often group 3) are sometimes excluded. The lanthanide and actinide elements (the f-block) are called inner transition metals and are sometimes considered to be transition ...
Transition elements are elements that have partially filled d orbitals in their ground states or can form stable cations with incompletely filled d orbitals. They have unique properties such as high melting points, paramagnetism, colour and catalysis.
A transition metal is one which has an atom with an incompletely filled d orbital or which forms one or more stable ioons with incompletely filled d orbitals. The older definition: A transition metal is one which forms one or more stable ions which have incompletely filled d orbitals. Notice how similar these two definitions are.

Sep 12, 2022 · The polarity of bonds with transition metals varies based not only upon the electronegativities of the atoms involved but also upon the oxidation state of the transition metal. Remember that bond polarity is a continuous spectrum with electrons being shared evenly (covalent bonds) at one extreme and electrons being transferred completely (ionic bonds) at the other.
