The transition element that has lowest enthalpy of atomisation, is :
Options:
Answer:
A
Solution:
Zn has the lowest enthalpy of atomisation among the given elements due to its fully filled 3d¹⁰ configuration.
The 3d¹⁰4s² electronic configuration results in weak metallic bonding.
Therefore, less energy is required to separate Zn atoms into gaseous atoms.
Hence, Zn has the minimum enthalpy of atomisation. Correct Answer: (A) Zn
