Question

what is heat of atomization

Answer 1

Answer:

The enthalpy of atomization is the enthalpy change that accompanies the total separation of all atoms in a chemical substance. This is often represented by the symbol ΔₐₜHᵒ or ΔHₐₜᵒ. All bonds in the compound are broken in atomization and none are formed, so enthalpies of atomization are always positive.
