* Molecular Geometry: H₂S has a bent molecular geometry, similar to water (H₂O). This is due to the two lone pairs of electrons on the sulfur atom.

* Electronegativity: Sulfur is more electronegative than hydrogen. This means sulfur attracts the shared electrons in the H-S bonds more strongly.

* Cancellation of Dipole Moments: While each H-S bond has a slight dipole moment, the bent geometry means these dipoles cancel each other out. The molecule as a whole has a zero net dipole moment.

Therefore, dihydrogen monosulfide (H₂S) is a nonpolar molecule.
