The Rule of Seven refers to seven specific elements on the Periodic Table that share certain properties. These elements are hydrogen (H2), Oxygen (O2) Nitrogen (N2) Flourine (F2), chlorine (Cl2), bromine (Br2) and iodine (I2).
The positions of these seven elements form the shape of a 7 on the periodic table. The properties they share are these: They have the greatest stability in the diatomic (2 atom) form, and they are bonded covalently.
