Fatal Hydrogen Sulfide Release at Aghorn Waterflood Station

SOLVED:The elements oxygen and sulfur have similar chemical properties because they both have six electrons in their outermost electron shells. Indeed, both elements form molecules with two hydrogen atoms, water (H2 O) and hydrogen sulfide (H2 S). Surprisingly, at room temperature, water is a liquid, yet H2 S is a gas, despite sulfur being much larger and heavier than oxygen. Explain why this might be the case.
