Study Notes
Ion Formation
- Metallic elements (Group I to III) form cations by losing valence electrons to achieve a stable electronic configuration.
- The charge of the cation is equal to the group number of the element: Group I elements form +1 ions.
- Examples of cations: Na+ (Sodium), K+ (Potassium).
Anion Formation
- Non-metallic elements (Group V to VII) form anions by gaining electrons to achieve a stable electronic configuration.
- The charge of the anion is defined by the number of electrons gained.
- Examples of anions: F- (Fluorine), Cl- (Chlorine), with a charge of -1.
