Why do the transition elements exhibit higher enthalpies of atomisation?
The transition element exhibit higher enthalpies of atomisation because the atoms in these elements are closely packed and held together by strong metallic bonds. The metallic bond is formed as a result of the interaction of electrons in the outermost shell. Greater the number of valence electrons, stronger is the metallic bond.
