Isotopes: Atoms of an element that have a different number of neutrons and a different atomic weight than usual. In other words, isotopes are alternate forms of the same chemical element, so they always have the same number of protons as that element but a different number of neutrons.Oxidation numbers are assigned to elements using these rules: Rule 1: The oxidation number of an element in its free (uncombined) state is zero — for example, Al (s) or Zn (s). This is also true for elements found in nature as diatomic (two-atom) elements. Rule 3: The sum of all oxidation numbers in a neutral compound is zero.A plane of symmetry is a plane that cuts a molecule in half, yielding two halves that are mirror reflections of each other.
