Why transition metals have high melting and boiling points?
Answer :- The melting and boiling points of transition metals are high. The high melting and boiling points suggest that the atoms of these elements are held together by strong forces. This is due to the strong interactions of electrons in the partially filled d-sub-shells.
Due to presence of unpaired electron in their atoms, transition elements have stronger interatomic interaction and hence stronger bonding between atoms. This stronger bonding between atoms are very strong. As a result in high melting points and boiling points and hence enthalpies of atomisation.
