Document Summary

Ionic bonds: bond of electrostaic atracion between posiive and negaive ions. Ionic compounds: compounds that are held together by ionic bonds. Aabb a: metallic element, a: # of a, b: non-metallic element, b: # of b. Anions: base element name with end changed to ide + ion . Caions: elements + ion : li+ = lithium ion. Compound: lif , caion: li+ , anion: f: name: lithium fluoride. Polyatomic ions: ions composed of more than one atom. The atoms in a polyatomic ion are held together by covalent bonds. Covalent bond: sharing of electrons between atoms in a molecule.
