WebExceptions to the octet rule include hydrogen (H) and helium (He) that follow the duet rule instead. They are the first two elements of the periodic table and have a single electron shell which accommodates only 2 electrons. Other exceptions include some group 3 elements like boron (B) that contain three valence electrons. WebThe three most stable isotopes of hydrogen: protium ( A = 1), deuterium ( A = 2), and tritium ( A = 3). Hydrogen ( 1 H) has three naturally occurring isotopes, sometimes denoted 1 H , 2 H , and 3 H . 1 H and 2 H are stable, while 3 H has a half-life of 12.32 (2) years.
