美国sophmore化学题目求救.
The octet rule states that atoms need 8 valence shell electrons in order to have "full" outter shells.This makes them stable.So,when molecules are formed,they will form so each atom in the molecule has 8 electrons in the outter shell.
BUT,some molecules are OK and stable without having 8 valence electrons.
1.Look at Nitrogen Dioxide (NO2).Draw two possible Lewis Dot Structures for the molecule.
2.Explain why NO2 does not fufill the Octet Rule.(What is happening with both Nitrogen and Oxygen's electrons?)
3.Is NO2 a stable molecule?Where is it commonly made in nature?

1.(see picture)
2.It forms a big pi bond.(see picture)
3.No.Two NO2 molecules can form one N2O4 molecule.
N2 + O2 =lightening= 2NO
2NO + O2 == 2NO2
