The formal charge of the central nitrogen atom of dinitrogen sulfide is +1.
Formal charge refers to the presence of electrons on an atom when absent and present in the molecule.
Lewis structure is The structural representation of a compound in which the electrons existing around the atom are represented by points is called the Lewis point structure.
Three possible Lewis structures of dinitrogen sulfide are shown below.
But the best Lewis structure of these is the first. The central nitrogen atom has a positive charge and the sulfur atom has a negative charge. The charges on these atoms are the most stable and make compounds stable.
Therefore, the central nitrogen atom has a formal charge of +1.
