Periodic Table of Elements Questions

intermolecular forces created by temporary dipoles that result from the movement of electrons in the atoms within moleculesforce that forms between an unshared pair of electrons on one molecule and a hydrogen atom bonded to a strongly electronegative atom on another moleculeintermolecular forces resulting from the attraction of the negative portion of the dipole of a polar molecule to the positive portion of the dipole of an adjacent polar moleculethe mixing of two or more orbitals of different energy levels on the same atom to produce new hybrid orbitals
