en.wikipedia.org/wiki/Transition_metalThe IUPAC definition defines a transition metal as "an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete d sub-shell". Many scientists describe a "transition metal" as any element in the d-block of the periodic table, which includes groups 3 to 12 on the periodic table.
www.britannica.com/science/transition-metalTransition 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 and resulting properties of the elements so designated.
www.merriam-webster.com/dictionary/transition%20metalDefinition of transition metal. : any of various metallic elements (such as chromium, iron, and nickel) that have valence electrons in two shells instead of only one. — called also transition element.
www.thoughtco.com/transition-metals-606664According to the IUPAC, a transition metal is any element with a partially filled d electron sub-shell. This describes groups 3 through 12 on the periodic table, although the f-block elements (lanthanides and actinides, below the main body of the periodic table) are also transition metals.
chemdictionary.org/transition-metalsTransition metals posses metal like characteristic. It has high density, high boiling and high melting point. Metallic bond in transition metals are formed by the delocalization of unfilled d-orbitals. The attraction between two atoms involved in metallic bond is increased with the increase of electrons in d-orbitals.
study.com/academy/lesson/transition-metals-definition-list-properties.htmlTransition metals are kinds of metals that have electrons in d or f orbitals. Transition metals are in columns 3-12 of the periodic table and in the lanthanide and actinide series. Most transition...
www.britannica.com/science/.../Biological-functions-of-transition-metalsBiological functions of transition metals. Several transition metals are important to the chemistry of living systems, the most familiar examples being iron, cobalt, copper, and molybdenum. Iron is by far the most widespread and important transition metal that has a function in living systems; proteins containing iron participate in two main processes, oxygen transport and electron transfer (i.e., oxidation–reduction) reactions.
www.chemicalelements.com/groups/transition.htmlRare Earth Elements. The 38 elements in groups 3 through 12 of the periodic table are called "transition metals". As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat. The interesting thing about transition metals is that their valence electrons, or the electrons they use to combine with other elements, are present in more than one shell.

chemed.chem.purdue.edu/genchem/topicreview/bp/ch12/trans.phpThe main group elements include the active metals in the two columns on the extreme left of the periodic table and the metals, semimetals, and nonmetals in the six columns on the far right. The transition metals are the metallic elements that serve as a bridge, or transition, between the two sides of the table.
