i. o2 is chemically bonded together.

ii. o2 is divisible.

iii. oxygen is a nonmetal.

iv. the natural state of oxygen is as a diatomic gas.
which conclusion can be drawn from these statements about o2?
a) o2 is an atom.
b) o2 is a molecule.
c) o2 is an electron.
d) o2 is an element.

Answer is: B) O2 is a molecule.

Pure substance is made of only one type of atom (element) or only one type of molecule (compound).

For example, hydrogen peroxide (H₂O₂), sodium chloride (NaCl) are compounds, lithium (Li) is an element and oxygen (O₂) is a molecule.

Molecules can be homonuclear (molecule made of two atoms of the same element, in this example oxygen) and heteronuclear (molecule made of two different atoms, for example water).

it's 3.2 on edge, i just took the test.
