Ions and ionic compounds
- Simple ions
- Charged particles
- electrons lost/gained = the charge
- 3 gained = 3-
- 4 lost = 4+
- Electronic structure of ionic compouns
- sodium loses outer electron and becomes an Na+ ion
- Chlorine gains an electron to its outer shell and becomes a Cl- ion
- Magnesium looses 2 outer electrons and becomes a Mg2+ ion
- Oxygen gains 2 electrons on its outer shell and becomes an O2- ion
