how enthalpy of atomisation determines the standard electrode potential of elements?
The question asked does not belong to your class though a simple answer is provided below:
Enthalpy of atomisation is the amount of enthalpy change when a compound's bonds are broken and complete separation of all atoms of a chemical substance takes place. It is denoted by the symbol ΔHa.
For example: In H2, the enthalpy of atomisation is equal to bond dissociation energy of HH bond.
Standard electrode potentials is sum of enthalpy of atomisation, ionisation energy and hydration enthalpy. Hence enthalpy of atomisation determines the standard electrode potential.
