Element group 3 to12: Transition metals ( Periodic Table #3)
The
38 elements in groups 3 through 12 of the periodic table are called
"transition metals". The 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." These are called transition elements since they represent a transition i.e., there is a change from metallic character of s-block elements to non-metallic character of p-block elements through d-block elements which are also 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.
This is the reason why they often exhibit several common oxidation states.
There are three noteworthy elements in the transition metals family. These
elements are iron, cobalt, and nickel, and they are the only elements known to
produce a magnetic field.
