Violations of the Octet Rule - Chemistry LibreTexts

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. WebFluorine is a second period element which can only contain a maximum of 8 valence electrons. Xenon meanwhile can have an expanded octet and can hold more than 8 electrons. Basically any of the fluorine atoms wouldn't be able to hold onto an extra 2 electrons which only leaves the central xenon atom with the ability to. Hope that helps. fisher editing
