Question

There are two valence electrons in an atom of magnesium. What would that magnesium atom do in a chemical reaction with another element?

Answer 1

Answer:

When a magnesium atom reacts with an oxygen atom, magnesium gives up its two valence electrons and becomes a positively charged ion, i.e. a cation, Mg2+ … The cation and the anion will then be attracted to each other by way of the electrostatic force of attraction → an ionic bond is formed.
