How To Identify The Number of Lone Pairs on an Atom Using Formal Charge:
Dots = Valence Electrons - [Formal Charge + Bonds] (1) Determine the number of valence electrons of the atom using the periodic table. (2) Count the number of bonds attached to the atom. A double bond has a value of 2 and a triple bond has a value of 3. (3) Using The formal charge, plug in the values into the formula above. A value of 1 indicates the atom is a radical. 2 dots indicate that there is 1 lone pair. 4 dots is equivalent to 2 lone pairs. A value of 3 indicates the atom is a radical with a lone pair.
