The video tutorial explains how to find the number of lone pairs in carbon monoxide (CO) by using a valid Lewis structure. It describes the difference between lone pair electrons, which are not involved in chemical bonds, and bonded pairs of electrons, which are shared between atoms. The tutorial identifies two lone pairs and three bonded pairs in CO, providing a clear understanding of the electron distribution in the molecule.

• Measuring the bond length

• Identifying the type of bond

• Drawing a valid Lewis structure

• Counting the total number of electrons
