Introduction
The three series of elements situated in the periodic table following the alkaline earth metals are described as transition metal; this term is sometime extended to include the lanthanide and actinide elements.
There position in the periodic table is between the s-block and p-block elements, their properties are transitional between the highly reactive metallic elements in the s-block, which typically form ionic compounds, and the elements of the p-block, which are largely covalent. In the s- and p-block electrons are added to the outer shell of the atom, in the d-block el…
