Question

What is bond energy? Why is it called enthalpy of atomisation?

✓

Answer

Bond energy is the amount of energy released when bonds are formed between isolated atoms in gaseous state to form one mole of gaseous molecule. It is called enthalpy of atomisation because it may also be defined as the amount of energy required to dissociate bonds present between the atoms of 1 mole of a gaseous molecule into constituting atoms.
