what is o2 the chemical symbol for?

Answer 1

Oxygen gas. Note that it is important to refer to it as Oxygen GAS. Caling it Oxygen is incorrect; Oxygen alone is O. O2 is Oxygen gas, and O3 is ozone.

Answer 2

O2 Chemical Name

Answer 3

Oxygen is a chemical element with the chemical symbol O and atomic number 8.
Unbound oxygen (also called molecular dioxygen, O2, a diatomic molecule) first appeared in significant quantities on Earth during the Paleoproterozoic era (between 2.5 billion years ago and 1.6 billion years ago) as a product of the metabolic action of early anaerobes (archaea and bacteria). The presence of large amounts of free oxygen may have driven most of the organisms then living to extinction.
At standard temperature and pressure, oxygen exists as a diatomic molecule with the formula O2, in which the two oxygen atoms are doubly bonded to each other. In its most stable form, oxygen exists as a diradical (triplet oxygen) with two unpaired electrons in molecular orbitals of the O2 molecule.

Answer 4

Oxygen gas. O2 is the symbol for the oxygen molecule.

Answer 6

Dioxide, di means the number 2 and oxide means more than one oxygen molecule present.

If on a periodiac chart, then it is just refered to as oxygen. They mark it as O2, because oxygen is not found standing alone in its natural state.

I should make myself clearer with the dioxide thing, that term is used when Oxygen is hooked with another molecule, say like Carbon.

CO2= Carbon Dioxide

Answer 7

Technically, O is the symbol for oxygen. O2 refers to a molecule of oxygen, two oxygen atoms joined together. Oxygen is a diatomic molecule, that is, it is only found naturally as O2, and not simply as O.

Answer 8

Actually its for an Oxygen molecule, Oxygen is O on the periodic table but it cannot exist as a single molecule so it will always join with something else. It has 2 free electron so it will join with something which takes up this space, ie H2O hydrogen has 1 free electron and Carobon has 4 free so it will be CO2

Answer 9

Oxygen

o2 is also a phone company LOL. A gd 1 at tht.

Answer 10

I cracked up at "Beccy24"s answer. HER, making fun of YOU, because you don't recognize O2 as being "water!"

I see this all the time in "Yahoo Answers." Someone making fun of another for not knowing an answer, as if THEY were somhow born with the knowledge, and never went through a period before a subject was learned.

And then the others, who offer ablsolutely WRONG answers with complete confidence in THEIR knowledge.

Now, "Beccy24" comes in with BOTH attitudes. Oh! How I wish there was a way to be sure she, and those like her, would come back to read how we respond to their naivte.
