Question

Why does oxygen exit as a diatom molecule while the other elements in the Group 16 exist as polyatomic molecules? Calculate the number of unpaired electrons in O2+ and O2`2- ions by drawing molecular orbital diagram

Answer 1

The molecule oxygen o2 have unpaired electrons. according to the molecular orbital diagram,in the Lewis structure, the number of valence electrons, which happen to be even, no electrons are unpaired.
