- Transition metals in 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. (wikipedia.org)
- The lanthanide and actinide elements (the f-block) are called inner transition metals and are sometimes considered to be transition metals as well. (wikipedia.org)
- All of the elements that are ferromagnetic near room temperature are transition metals (iron, cobalt and nickel) or inner transition metals (gadolinium). (wikipedia.org)
- The group 12 elements zinc, cadmium, and mercury are sometimes excluded from the transition metals. (wikipedia.org)
- The group 12 elements Zn, Cd and Hg may therefore, under certain criteria, be classed as post-transition metals in this case. (wikipedia.org)
- The recent (though disputed and so far not reproduced independently) synthesis of mercury(IV) fluoride (HgF 4) has been taken by some to reinforce the view that the group 12 elements should be considered transition metals, but some authors still consider this compound to be exceptional.
