# 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^-

Dec 30, 2016

#### Answer:

$M g \left(g\right) + \Delta \rightarrow M {g}^{+} \left(g\right) + {e}^{-}$

This is subject to measurement.............

#### Explanation:

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.
