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

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 $\left(\Delta \text{EN}\right)$ 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.
