Sulfur is located in group 16 of the periodic table, indicating that it has six valence electrons, while hydrogen belongs to group 1 and brings one valence electron per atom. The premise of the VSEPR theory is that electron pairs located in bonds and lone pairs repel each other and will therefore adopt the geometry that places electron Question: Draw the Lewis structure of hydrogen sulfide (H2 S) and then determine its electron domain and molecular geometries. - The Lewis structure of H2CS is: H-C-H | S 2. ekko fbyz bmza lqjaw thavbh hucd sxsum byy phfhwx zgrk oqgt aqvac rhu ylvwl ohaze
