He

SO2

Answer 1

idk sorry

Answer 2

Helium and Sodium Chloride

Answer 3

oxygen is an element, but it occurs naturally as a diatomic molecule

Answer 4

i dont think this question makes sense, as a molecule needs to be at least 2 atoms.

If it's more than 2 atoms, then it cannot be an element.

Answer 5

^i agree, if you have to choose one, then choose \(O_2\)

Answer 6

I am very confused...

Answer 7

oxygen occurs in nature not as single atoms, but as two bonded oxygen atoms (its a molecule). but oxygen is still an element

Answer 8

Okay, thank you :)
