Answer:
Zero Lone Pairs
Step-by-step explanation:
Hydrogen Sulfate is made from Sulfuric acid. It is an ion and contains a negative charge on one of its oxygen atoms. The central atom of this ion is sulfur atom.
The lewis structure of hydrogen sulfate is attached below. It can be seen from the structure that the sulfur is carrying no lone pair of electrons as that carried by oxygen atoms. The sulfur atom is making four single or multiple bonds with oxygen atoms. Also, the electron and molecular geometry around sulfur is Tetrahedral.
