WebHowever, some of noble gas elements like Xenon have formed compounds with fluorine and oxygen. For example: XeF 2, XeF 4 etc. Therefore, validity of the octet rule has been challenged. This theory does not account for shape of molecules.

To physicists, this was not obvious that two negatively charged particles could be “paired”. lauren tokashWebKossel and Lewis treated the positively charged nucleus and inner electrons as the center of a cube whose 8 corners are occupied by the valence electrons. They stated that chemical bonds are formed between atoms to achieve stability, by respective gain and loss of electrons. Langmuir abandoned the idea of treating the atom as a stationary cube. lauren tobiassen
