Gilbert Lewis introduced this rule to explain the chemical inertness of noble gases.
This rule was born out of the Abegg's rule, which concerns the difference between the maximum and minimum valences that an element can take. The 3-center-4-electron model explains the violation of this rule by hypervalent molecules. This rule is also violated in molecules such as boron trifluoride and free radicals such as nitric oxide, both of which react to obey this rule. Gilbert Lewis introduced this rule to explain the chemical inertness of noble gases. For 10 points, identify this chemical rule that states that atoms seek to attain a configuration with eight outer electrons.
This rule was born out of the Abegg's rule, which concerns the difference between the maximum and minimum valences that an element can take.
