Why are the properties of sulfur, selenium, tellurium, and polo... | Filo

SOLVED: A biochemist who is studying the properties of certain sulfur (S)-containing compounds in the body wonders whether trace amounts of another nonmetallic element might have similar behavior. To which element should she turn her attention? (a) F (b) As (c) Se (d) Cr (e) P

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. | Numerade
