उत्तर
No. The values are not matched correctly.
Explanation:
Zinc has a lower enthalpy of atomisation (~130 kJ mol−1) because its configuration [Ar]3d104s2 has no unpaired electrons, resulting in weaker metallic bonding.
Copper has a higher enthalpy of atomisation (~339 kJ mol−1) due to the presence of one unpaired electron in its 3d94s1 configuration, which leads to stronger metallic bonding.
