Question

Why do transition metals have high enthalpies of atomisation?

Answer 1

ransition elements have high effective nuclear charge and a large number of valence electrons. Therefore, they form very strong metallic bonds or metal-metal bonding. As a result, the enthalpy of atomisation of transition metals is high.

Answer 2

Answer:

• Transition elements have high effective nuclear charge and a large number of valence electrons.
• Therefore, they form very strong metallic bonds.
• As a result, the enthalpy of atomization of transition metals is high.
