How do you complete the following equation to illustrate the first ionization energy for one mole of magnesium atoms: #Mg:(g) + ? kcal -> Mg(g) + e^-#
This is subject to measurement.............
All science relies on data, and to get these data, we need measurement. I don't know how they measure the ionization energy of magnesium metal, but I know that it is available become someone has measured it.
