If you label the oxygen atoms A, B and C, as shown below, then A has a double bond in 1/3 of the structures you could draw, but it would have a single bond in the other 2/3 of the ways in which you could draw the structure. The same is true for the atoms B and C. In fact, carbonate really has about 1-1/3 bonds between each carbon and oxygen. The molecular orbital electronic configuration of Homonuclear Diatomic Molecule H2 is: Therefore, there is a covalent bond between the two hydrogen C2 molecule consists of both the pi bonds because of the presence of 4 electrons in two pi MOs. While in other molecules, a double bond is...

Occasionally, you'll have to find the Lewis structure for a polyatomic ion. To do so, subtract the ionic charge from the valence electron count. For example, NH 4 + will have one fewer valence electron that the nitrogen and four hydrogens would have because it has a +1 charge. Step 2. Count the total octet electron count in the molecule.
