Ionic bonds occur between a ___________________ and a nonmetal. The metal forms a cation with a
__________________ charge when it loses electrons while the nonmetal forms a(n) _______________ with a
negative charge when it __________ electrons. ____________________ attraction occurs between the cation
and anion.
____________________ bonds are made up of shared electrons around the nuclei of multiple atoms of a
metal. This “sea of valence ___________________” give metals their distinctive properties like being good
___________________ and their malleability and ductility. Malleability is the ability of a metal to be
________________ into sheets and ________________ is the ability to be pulled into wires.
Covalent bonds form when electrons are ________________ between nonmetals. Covalently bonded
compounds can have single, _________________ or triple bonds.
Intermolecular forces occur between _____________________. Polar forces exist if electrons are shared
unequally, creating two areas of charge, or _____________, in a molecule. One type of dipole is the
hydrogen bond. Hydrogen bonds exist between ________________ on one molecule and highly
electronegative atoms (like fluorine, oxygen or nitrogen) on another molecule. Nonpolar forces exist between
molecules that have equal internal sharing of their electrons. These nonpolar forces are called ____________
______________ forces and are relatively weak.
