Is O2 a molecule

Answer 1

Yes, oxygen exists in the atmosphere as a molecule consisting of two oxygen atoms. It is also a component in other gaseous compounds normally found in air, as well as many solid and liquid compounds.

Answer 2

O2 is the chemical formula for a reactive gas known as oxygen. Oxygen is a component of hundreds of thousands organic compounds. However, O2 itself is not an organic molecule because in order for something to be organic it has to either contain carbon or has to be covalently bonded to another element that contains carbon. Typically, organic molecules contain carbon and hydrogen bonded together.

Answer 3

You wouldn't write it that way; the system is very easy to understand:

Organic molecules: carbon is written first, then hydrogen and then the rest of the elements in alphabetical order.

Inorganic molecules: elements listed in alphabetical order.

There are some special cases, but in a school science lab you're not too likely to tangle with salts of amines or homopolymers.

Given that, let's reformat your formula:

HO2

Which would look like...

H - O - O

You see the open bonding site at the end of the chain...which, knowing this ligand, isn't going to remain open very long. It will grab the first thing it sees, and it would prefer to take one of the very abundant Hydrogen atoms, giving you

H - O - O - H

Written out in standard format it's H2O2...our good friend hydrogen peroxide.

Answer 4

Yes, it is a molecule. Its name is Oxygen gas (O2).

Answer 5

It's both. Confusing, but true. Oxygen always pairs with a second oxygen to form O2.

So do several other gases.

Answer 6

Oxygen is an atomic element. It is found in many molecules.

Answer 7

Yes, Oxygen gas is a molecule, made up of two atoms of Oxygen..

Answer 8

O2 is a diatomic molecule.
