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 ...

Die chemischen Elemente mit den Ordnungszahlen von 21 bis 30, 39 bis 48, 57 bis 80 und 89 bis 112 werden üblicherweise als Übergangselemente bezeichnet. Da diese Elemente alle Metalle sind, wird auch der Ausdruck Übergangsmetalle benutzt. Dieser Name ist in ihrer Position im Periodensystem begründet, da sich dort der Übergang ...
23. Apr. 2024 · Learn about the 24 chemical elements that have two shells of valence electrons and form compounds in two or more oxidation states. Find out their general properties, subdivisions, and examples of the first, second, and third transition series.
12. Sept. 2022 · Transition metals exhibit chemical behavior typical of metals. For example, they oxidize in air upon heating and react with elemental halogens to form halides. Those elements that lie above hydrogen in the activity series react with acids, producing salts and hydrogen gas. Oxides, hydroxides, and carbonates of transition metal ...
