WebCHEM-111G-GENERAL CHEMISTRY I The octet rule indicates that: 1. the noble gases react with other compounds to get 8 valence electrons. 2. all of the noble gases have eight total electrons. 3. all of the shells in an atom hold a maximum of 8 electrons. 4. all of the Group A elements have 8 valence electrons. WebDec 5, 2024 · You can expand an octet of an atom if it is in the the 3p orbital because then it can access its 3d orbital. It is done to remove formal charge. With resonance structures, you are often trying to reduce the formal charge on each individual atom, and it often leads to accessing the d orbital to expand its octet.
