- Ions are electrically charged particles formed when atoms lose or gain electrons
- Have the same electronic structures as noble gases.
- Metal atoms form positive ions.
- Non-metal atoms form negative ions.
- The strong electrostatic forces of attraction between oppositely charged ions are called ionic bonds.
- The number of charges on an ion formed by a metal is equal to the group number of the metal
- The number of charges on an ion formed by a non-metal is equal to the group number minus eight
- Hydrogen forms H+ ions.
- Sodium is also in Group 1. It has one electron in its highest energy level. When this electron is lost, a sodium ion Na+ is formed.
- Calcium is also in Group 2. It has two electrons in its highest energy level. When these electrons are lost, a calcium ion Ca2+ is…
