How do you define atomic state?
Some elements that are not chemically combined with any other substance exist as single atoms. Pure copper, pure lead, pure silver. Oxygen does not, the pure state of oxygen is a diatomic molecule, O2.
Is o2 a substance?
O2 is in fact a very pure substance. O2 is a pure substance because it's only atoms are oxygen atoms.
Is oxygen mixture or pure substance?
