The formal charge of the nitrogen atom present at the center in dinitrogen sulfide is +1.
Formal charge:
The formal charge relates the presence of electrons on the atom when it is not present in a molecule and when it present in a molecule.
Lewis structure:
The structural representation of a compound by showing the electrons present around the atom with dots is called the Lewis dot structure.
The three possible Lewis structures of dinitrogen sulfide are shown below.
However, the best Lewis structure among those is first one. The central nitrogen atom is carrying a positive charge while the sulfur atom has a negative charge. The charges on these atoms are most stable thereby making the compound stable.
Therefore, the formal charge on the central nitrogen atom is +1.
