The d-block elements, which are also called the transition metals, do not have the extreme variability in chemistry among the p block elements. Instead, these elements exhibit significant horizontal and vertical similarities in chemistry, and all have a common set of characteristic properties due to partially filled d subshells. The d-block elements are located between group 2 and 13 of the periodic table. Transition metals are metals with low ionization energies that exhibit often multiple possible oxidation states.
