Text Solution

AI Generated Solution

To understand why the enthalpy of atomization of zinc is the lowest in the 3d series, we can break down the explanation into several steps: ### Step-by-Step Solution: 1. **Definition of Enthalpy of Atomization**: - The enthalpy of atomization is defined as the amount of energy required to break one mole of bonds in a substance to form gaseous atoms. In simpler terms, it measures how much energy is needed to convert a solid metal into its gaseous atomic form. 2. **Understanding Zinc in the 3d Series**: ...
