bond angle | angle at which adjacent atoms in a molecule are attached | |
electron dot structure | a notion that depicts valence electrons as dots around the atomic symbol of the element | |
hybridization | a process in which several atomic orbital S mix to form the same number of equivalent hybrid orbitals | |
octet rule | atoms react by gaining or losing electrons so as to acquire the stable electron of a noble gas | |
anion | an atom or group of atoms with a negative charge | |
cation | an atom or group of atoms with a positive charge | |
polar molecule | a molecule like water in which 1 or more is slightly positive | |
structural formula | a chemical formula that shows the arrangement of atoms in a molecule or a polyatomic ion | |
unshared pair | a pair of valence electrons that is not involved in bonding | |
valence electrons | an electron in the highest occupied energy level of an atom | |
VSEPR theory | valence-shell elecron pair repulsion theory | |
van der Waals forces | a form used to describe the weakest intermolecular attractions | |
dispersion force | the weakest kind of ntermolecular attraction | |
hydrogen bond | a relatively strong intermolecular force in which a hydron bond atom that is covalently bonded to a very electronegative atom is also weakly bonded to an unshared electron pair of another elecronegative atom in the same molecule |
