- In a covalent diatomic molecule, a difference in the electronegativity of the atoms will result in a dipole moment.
- The three shared pairs of electrons between the two carbon atoms create a triple covalent bond.
- Pairs of electrons that are not shared in covalent bonds are lone pairs.
- These rules are the result of assigning all electrons in a covalent bond to the more electronegative atom in the bond.
- To complete an octet, each oxygen must share two electrons in a covalent bond.
