Study Notes
Ions
- Ions are atoms with a charge.
- Cations are positively charged ions that have more protons than electrons.
- Anions are negatively charged ions that have more electrons than protons.
Formation of Ions
- Cations are formed when atoms lose electrons.
- Anions are formed when atoms gain electrons.
Attraction of Ions
- Oppositely charged ions attract each other.
- Cations and anions attract because of this.
Electrical Conductivity of Ions
- Moving ions can conduct electricity.
- Compounds must have no total charge to be stable.
- To achieve this, compounds balance their cations and anions to have a net charge of zero.
