[total # valence electrons] - [# lone electrons + 1/2(# paired electrons)]
20 - [4+1/2(10)] = 11
So, 11 is the formal charge.

The ternary acid formed with chlorine that has the fewest oxygen atoms is hypochlorous acid (HClO).
Chlorine is a negatively charged ion, known as chloride (Cl-).
The formal charge of nitrite (NO2-) is -1. Each oxygen atom carries a formal charge of -1, while the nitrogen atom carries a formal charge of +1, leading to an overall charge of -1 for the nitrite ion.
The total charge of chlorine is -1. Chlorine typically forms an anion with a charge of -1 by gaining one electron to achieve a stable electron configuration.
Chlorine typically has a charge of -1 when it forms an ion.
