WebMelting and boiling point of d-block elements The transition metals are very hard and have low volatility. Their melting and boiling points are high. The high melting point of these metals are attributed to the involvement of greater number of electrons from ( n-1)d in addition to the ns electrons in the inter atomic metallic bonding. definition Webd-block elements with more number of unpaired e − have high boiling points as more is the number of unpaired e −, stronger is the metallic bonding which results in high enthalpy of atomization. Thus more amount of heat is required to weaken these metallic bonds. Hence having a high boiling point.
