... By looking at the Lewis Dot Diagram for oxygen, you can see that oxygen has two unpaired electrons, so it has two electrons available for standard bonds. These unpaired electrons might make two single covalent bonds (e.g., water (H2O)) or they might make one double covalent bond, as the case of magn ...
