Which one of the following compounds does not follow the octet rule? Phosphorous atom has five valence electrons in its outermost shell and it is capable of forming three covalent bonds with the neighboring atom to complete its octet. A valid Lewis structure of _____ cannot be drawn without violating the octet rule. Following the octet rule results in completely filled s- and p- orbitals in an atom's outermost energy level. The Lewis structure for PH3 contains an atom that does not follow the octet rule False In the valence shell electron pair repulsion theory, a group is defined as an atom or lone pair of electrons Oxygen has 6 valence electrons, the bonds should be 8-6=2 bonds. The octet rule may not also apply to certain elements, like phosphorous and sulfur, both of which can have 12 bonded electrons when bonded to 6 other atoms (SF6 is an example), and boron, which can show up in configurations with less than 8 valence electrons like BF3. How does calcium follow the octet rule? One exception to the octet rule is that in the real world some atoms in molecules or compounds do have fewer than eight (octet) valence electrons. So it shares 3 single bonds with chlorine in order to gain stability. A. no it does not follow . (Both Group III elements). Chemistry. Best Answer.
