Ionic Bonding

• Cation is a positively charged ion that loses electrons
• Octet Rule states that a shell should have 8 electrons; shells can either lose or gain electrons in Ionic Bonding
• Metals and nonmetals in Ionic Bonding

  • Metals are usually positive (+)
  • Nonmetals are usually negative (-)
• When you see a positive charge, the atom is losing an electron; when you see a negative charge, the atom is gaining an electron
• Ionic Bonds consist of a positive (+) and a negative (-) charge
• Valence Electrons


  Electrons in the outermost shell used to help with bonding
• Nearly all metals form cations
• Ions are atoms with a charge
• Ionic Bond

  Force of attraction between a positive charge and a negative charge
• Ionic Bonding

  1. Forms between 2 or more atoms by transfer of 1 or more electrons between atoms

  2. An atom either gains or loses electrons in this type of bonding

  3. Opposite charges attract

  4. Transfers valence electrons between atoms
• Fluorine, Oxygen, and Nitrogen are electron-negative elements
• Atoms tend to gain, lose, or share electrons to try to have 8 electrons in their outer shell
• Atoms gain or lose electrons in order to achieve the Octet Rule
• Anion is a negatively charged ion that gains electrons
• Fluorine has the highest electron negativity.
