Exceptions to the Octet Rule
Some of the exceptions to this rule are listed below. An ion atom or a molecule containing an unpaired valence electron is called a free radical. These Are The Exceptions To The Octet Rule An electron or molecule which contains unpaired electrons in its outermost shell or valence shell is considered a free radical. . Since the first shell can only accommodate. Elements on the 3rd Period 3rd row of the periodic table and below can actually have more than 8 electrons around them. Hydrogen H only requires 2 electrons to have a full valence shell since it only needs to be like Helium He. Then the action in the matching rule is executed. Many elements do not follow the octet rule. An electron shell is the set of allowed states that share the same principal quantum number n the number before the letter in the orbital label that electrons.
