Key words...
Ionic Bonds - valence electrons are transferred

  • Properties of an ionic bond
  • Formed between a metal and a non-metal element
  • Loss or gain of electrons forms an ion
  • Crystal structure is alternating (+) and (-) ions held together by electrostatic forces
  • Electrostatic force is the force holding together a (+) and (-) ion
  • Loss of an electron forms a positive (+) ion
  • Metals tend to form (+) ions
  • Loss of an electron forms a negative (-) ion
  • Nonmetals tend to form (-) ions
  • Oxidation number is the charge on an element when it loses or gains an electron

Covalent Bond - valence electrons are shared

  • Properties of a covalent bond
  • Formed between two non-metal elements
  • Bonding electrons are in the outer most level

  • Properties of metallic bonds


Polyatomic ion is a group of elements that acts like a single ion
Monatomic ion is a single element ion
