Why do transition metals exhibit higher enthalpy of atomization?
Advertisements
उत्तर
Enthalpy of Atomisatioun α number of volence electrons
→ Greater the number of valence electrons. stronger is the resultant bonding.
→ For transition metals, more is (n -1) d electrons and n s electrons so more is intermetallic bonding. So, higher is enthalpy of Atomisation for Transmition metals.
