Apr 23, 2024 · Learn about the 24 chemical elements that have valence electrons in two shells and form compounds in two or more oxidation states. Find out their general properties, subdivisions, and examples of technologically important transition metals.
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 ...

Why are these elements often referred to as “\(d\)-block” elements? Why do many transition element compounds have bright colors?
Sep 20, 2023 · Learn about the transition metals, the largest group of elements on the periodic table, and their properties, such as color, magnetism, conductivity, and alloys. Find out the list of 40 transition metals according to the IUPAC definition, and the exceptions and variations of some elements.
Jul 12, 2023 · It is useful, at the beginning, to identify the physical and chemical properties of transition elements which differ from main group elements (s-block). Properties of transition elements include: have large charge/radius ratio; are hard and have high densities; have high melting and boiling points; form compounds which are often paramagnetic;
Sep 12, 2022 · The transition metals are elements with partially filled d orbitals, located in the d-block of the periodic table. The reactivity of the transition elements varies widely from very active metals such as scandium and iron to almost inert elements, such as the platinum metals.
James Ng. 9 years ago. Transition metals usually have a partially filled d-subshell. This allows the reagents to form temporary bonds with the metal and the intra-molecular bonds of reagents are weaken as a result. The weaker intra-molecular bonds require a lower activation energy to overcome.
