Ionic Compounds all form in a similar way

Dot and cross diagrams show what happens to the electrons when ionic bonding happens

Sodium Chloride (NaCl)

The sodium atom gives up its outer electron, becoming an Na+ ion. The chlorine atom picks up the electron, becoming a Cl- ion. 

Magneisum Oxide

The magnesium gives up its two outer electrons, becoming an Mg2+ ion. The oxygen atom picks up the electrons, becoming an O2- ion.

Sodium Oxide (Na2O)

Two sodium atoms give up their outer electrons, becoming two Na+ ions. The oxygen atom picks up the two electrons, becoming an 02- ion.

Calcium Chloride (CaCl2)

The calcium atom gives up its two outer electrons…
