Ions

Ions = Charged Particles 

  1. Ions are formed when atoms gain or lose electrons.
  2. Positive ions (cations) are formed when a neutral atom loses electrons.
  3. Negative ions (anions) are formed when a neutral atom gains electrons.
  4. Metallic atoms tend to lose electrons to form positive ions (also known as cations).
  5. Nonmetallic atoms tend to gain electrons to form negative ions (a.k.a. anions).
