Question
Write note on enthalpy of atomization of trasition metals.
✓
Answer
→ The transition elements have high enthalpy of atomization because of presence of strong bonds between the atoms.
→ The enthalpy of atomisation increases with the increase in number of unpaired electrons which results in formation of strong bonds due to strong interatomic interactions.
→ The metals of the second and third series have greater enthalpies of atomisation than the corresponding elements of the first series; this is an important factor in accounting for the occurrence of much more frequent metal - metal bonding in compounds of the heavy transition metals.
