Why are all diatomic molecules diatomic molecules linear, regardless of the number of valence electron pairs on the atom?
i don't understand this question
what is meant by linear?
Linear means that the atoms lie on a straight line. You can't draw H-H, N-N, O-O, F-F, Cl-Cl, Br-Br, etc any other way than a straight line. Of course you can draw them as
BUT that's still a straight line.
