Answer
The bond between a hydrogen atom and a sulfur atom is nonpolar covalent, so the electrons are shared.
Explanation:Comparing their electronegativities will help determine the type of bond. Electronegativity is the tendency of a bonded atom to attract shared electrons to itself. The difference in electronegativity (ΔEN) is used to determine bond type. Hydrogen has an electronegativity of 2.20 and sulfur has an electronegativity of 2.58. The electronegativity difference is 0.38. The electrons are shared in a nonpolar covalent bond.
