Question

Which element of 3d series has lowest enthalpy of atomisation?

Answer 1

Answer:

Due to the absence of unpaired electrons in ns and (n–1)d shells, the interatomic electronic bonding is the weakest in zinc. Consequently, zinc has the least enthalpy of atomisation in the 3d series of transition elements

Explanation:

hey its answer i hope its helpful

Answer 2

Zinc is the 3d series that has lowest enthalpy of atomisation
