What's the difference between work function and ionisation energy?
I thought they were the same thing, but apparently not

Isn't the work function the minimum energy needed for an electron to escape the surface of a metal (the most loosely bound electron). The ionisation energy is the amount of energy required to remove one mole of electrons from an element in its gaseous phase to produce one mole of unipostive gaseous ions. Thus the difference is work function is the amount to remove an electron from a metal, and ionisation is in gaseous form and concerns a mole of the substance in question.
