The octet rule indicates that all of the shells in an atom hold a maximum of 8 electrons. the noble gases react with other compounds to get 8 valence electrons. all of the noble gases have eight total electrons. all of the Group A elements have 8 valence electrons. atoms lose, gain, or share valence electrons to have 8 valence electrons.

The octet rule is a chemical rule of thumb that reflects the theory that atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas. Show more…

Octet Rule states that atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas. Depending on this fact answer the following question : 1)What is an incomplete octet?2)What is an odd-electron molecule?3)Why are there extra electrons in the expanded octet?

Unlike other elements, noble gases are relatively inert. When noble gases do react, they do not follow the octet rule. Examine the following Lewis structure for the molecule $\mathrm{XeO}_{2} \mathrm{F}_{2}.$ a. Explain why the valence electrons of Xe do not follow the octet rule. b. How many unshared pairs of electrons are in this molecule? c. How many electrons make up all of the shared pairs in this molecule?
