can oxygen be found in it's elemental form?

Yes, rocket fuel (seriously).

Not sure what you mean. But here is two possible answers for you anyways.\n\n1) Oxygen which can also exist as Ozone (O3) which is a Triatomic molecule.\n2) Or like IDUNNO pointed out Astatine which is usually not considered because of its rarity in nature.

At the moment it's Oxygen. It's part of "all I need is the air that I breathe"\nhttp://www.lyricsfreak.com/h/hollies/65683.html\n\nIn awhile it will be both Hydrogen and Oxygen for a drink of water.\n\nAt dinner tonight add Carbon, Nitrogen and various trace elements in the New York Cut Steak!\n\nFor info on any element click on the Periodic Table of Elements at this site.\nhttp://environmentalchemistry.com/yogi/periodic/

One molecule of Oxygen is referred as Oxygen atom.  When two of these are fused together (by reaction), it is called Oxygen (exists in gas phase but can also exist as liquid under high pressure).  When three atoms are fused together, it is called Ozone.  Yes, the same one you hear about making hole in the atomosphere.  I am assuming that you are a bigginer chemist so I will not go through scientifc discussions regarding this chemical reaction.  If you are interested, post me anote and I will explain in details.

Generally Group I and Group II elements form ionic compounds with non-metals. Hence for all of the metals above, they should form ionic compounds with oxygen.\nSodium - Na+; oxide - O2-\nHence you need 2 sodium ions to calcen out the -2 charge on the oxide ion, and the formula of sodium oxide is Na2O.\nSimilarly for potassium oxide, K2O.\nCalcium - Ca2+, oxide - O2-\n1 of each is needed to cancel out the charges, hence the formula CaO.\nSimilarly for MgO.\nAns: Na2O, K2O, MgO and CaO\n\nHope this helps :)

Well adding upto the given answers above, I would like to say it is not the only reason noble elements may form compounds. Compound like XeF4 are formed because Xe has a lot of non bonding electrons. It can donate it to form more compounds. Here are some links where you will find some neon and even helium compounds formed!!

trying to be a smart ass huh? well if you are not then here is the answer.\n\n"FREE" hydrogen and "FREE" oxygen mixed together is highly explosive, however a Hydrogen Oxygen "COMPOUND"(water) is not.

I dont understand what you mean by "correcting certain formulas", but it appears Fe bears +1 oxidation state, if oxygen is -2. However, Fe does not bear such oxidation state, normally; it can bear 0, +2, +3, +4 and +6. With oxygen, what you will get, most likely, are FeO and Fe2O3. So, I would expect the the compound was a mixture of iron metal and one/several of these oxides. It appears that your compound could be 1:1 mixture of iron and iron(II) oxide.\n\nIf the question states that the compound was pure, check your calculation again; if you have done nothing wrong, the compound could be iron(II) peroxide [iron bears +2, oxygen bears -1]; it's not stable [I'm not sure whether it exists or not], or the strange iron(I) oxide [again, never seen this compound before, not sure it actually exists or not].

yes, they always covalently bond with each other under any normal type conditions\n\neven if you were to conveniently have an oxygen cation and anion that you combined, they would lose their ionic nature and bind in a covalent fashion

Most oxygen compounds do have an octet.  Nirtogen compounds suffer from nitrogen having an odd number of valence electrons.  Still most nitrogen compounds tend to follow the octet rule.

Some of the elements while in gaseous state.

Actually, there are a few things wrong with that structure. If the Red atoms are indeed oxygen then the formal charge would be (C4H8O2)2-, the double minus change would make this very unstable. \n\nOxygen is only found by when it is double bonded, which it can't do here since carbon can only have four bonds. The red could be a halide, that is something from the F, Cl, Br and I column. \n\nIf the red guys were bromine then it would be \n2,3-dibromobutane

y are u asking homework questions?  Well one similarity is the they are diatomic so in other words they are always H2 or O2 when alone. ohh and the guy below me oxygen is explosive what we breath is mainly nitrogen.  so there i told u

francium. mercury is technicaly not a metal, it just has a low melting point, low metling points do not make it unstable. if that were the case, then oxygen would be VERY unstable ITS ALREADY TURNED INTO VAPOR!!!

The elements Chlorine and Nitrogen are found in their natural, elemental forms of Chlorine gas (Cl2) and Nitrogen gas (N2) in nature, not as atomic Chlorine or atomic Nitrogen.\n \nNitrogen gas makes up the majority of Earth's atmosphere (AKA "air").\n\nChlorine gas is faily easy to produce with electrochemical reactions, or even through standard (non electrolytic) reactions.\n\n\nClorox does NOT contain Chlorine gas.  Amongst other things, the active ingredient in clorox bleach is Sodium Hypochlorite (NaOCl), not "Chlorine".

One of these scientists, a man named Democritus, would sit here in the central market place of Athens, Greece, and explain to one and all how all things on earth and in the heavens are made of extremely tiny, simple particles. He called them "atoms.o/oo \n\n\nThus when the element hydrogen combines with the element oxygen, it must do so all or none. In the case of water, for instance, one atom of oxygen combines with two atoms of hydrogen. Now when oxygen combines with carbon to make carbon dioxide, two oxygen atoms combine with one carbon atom. And when they make carbon monoxide, it is one atom oxygen to one atom carbon. So, too, all other chemical compounds are made of a simple combination of a few basic atoms.
