THE POWER OF IONS AND HOW THEY ARE CREATED
How ions are formed
Ions form because they either gain or lose valence electrons. This is to fill the outermost energy level. This is how ions are formed.
Why do ions form?
Ions form because they want to be perfect. They try to fill the outermost energy level to even out.
How to determine the charges on ions
You can determine ions by finding the number of electrons gained or lost. If the atom gains electrons it would turn negative, if it loses electrons, it would turn positive.
