Molecule Unit of matter that results when two or more atoms are joined by covalent bonds Ionic Bond A bond resulting from the electrostatic attraction of a cation for an anion. Brainpower Read More Nonpolar Covalent Bond A bond characterized by an even distribution of charge; electrons in the bonds are shared equally by the two atoms Polar Covalent Bond A bond resulting from unequal sharing of bonding pairs of electrons between atoms Polyatomic Ions Charged g...

What are the 5 types of intermolecular forces? 1. Dispersion 2. Hydrogen bonding 3. Dipole-dipole 4. Ion-dipole 5. Ion-Ion Dispersion forces the weakest intermolecular force; a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles Hydrogen bonding forces stronger than dispersion forces its an attraction of hydrogen to O, F, and N Dipole-dipole forces intermolecular forces that exist between polar m...
