[Does no3 violate the octet rule does no3 violate the octet rule, Writing Lewis Structures: Octet Rule Violations. Xenon is a noble gas, but it forms a number of stable compounds. Write the Lewis structures of XeF 2 and XeF 6. Solution. Follow the six steps in section 7.3. In this case, we condense the steps. 1. Calculate the number of valence electrons: XeF 2: 8 + (2 × 7) = 22 XeF 6: 8 + (6 × 7) = 50. 2 and 3. ]
