the area around an atom where according to orbital theory the probability of finding an electron is the greatest. More Information
the quantum theory matter that combines Schrodinger's wave mechanics and Heisenburg's uncertainty principle and applies this to the behavior and nature of electrons. Orbital theory was formulated in 1926 and has yielded a better understanding of electrons and their critical role in chemical bonding than is possible with Newtonian mechanics.

Either the actual charge of an atom (ion) in a substance, assuming the atom exists as a monatomic ion, or a hypothetical charge assigned by simple rules. 2) The charge an atom would have in a substance if the pairs of electrons in each bond belonged to the more electronegative atom. 3) The number of electrons that must be added or subtracted from an atom in a combined state to convert it to the elemental form.
Generally the following rules for assigning oxidation numbers to an atom can be used:
