Answer:
Enthalpy of atomisation
The enthalpy of atomisation of an element is the enthalpy change when 1 mole of
gaseous atoms is formed from the element in its standard state
Na (s) = Na(g) [ΔatH = +148 kJ mol-1]
½ O2 (g) = O (g) [ΔatH = +249 kJ mol-1]
We havent learned about enthalpy of sublimation. Sorry :(
