Explain in brief, four series of transition elements. This allows the transition elements to form structures in which there are four, five or six attached species (see ligands below). They can form mono or polydentate ligands; The largest group of elements in the periodic table are the transition metals. Electrons in the outer shells of the atoms of these elements have little shielding effects resulting in an increase in effective nuclear charge due to the addition of protons in the nucleus. The metals having the highest melting and boiling points are towards the middle of each transition series.
