As a bond between a hydrogen atom and a sulphur atom is formed, are the electrons shared or transferred to form a covalent or ionic bond?

Solution
Answer The bond between a hydrogen atom and a sulphur 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 the bond type.
Hydrogen has an electronegativity of 2.20 and sulphur has an electronegativity of 2.58. The electronegativity difference is 0.38. The electrons are shared in a nonpolar covalent bond.
