  • 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…
