Oxygen is a chemical element.
Neither. The condensation of oxygen gas is a phase change. The oxygen itself would be an element, not a mixture.
Neither, it is a mixture of a variety of compounds.
Oxygen Gas is itself a co-valent compound. It's formula is O2 which means oxygen gas is an atom contains two O molecules. Except zero group element all gases are compound.
If you are talking about the gas we breath in the air, it's a compound. Pure oxygen as a gas exists as a molecule. Oxygen as an element, is unstable and as far as I know doesn't exist as a single element in nature. It will always occur in combination with something else, such as H2O or O2.
elementHydrogen as a gas, plasma, or liquid is still an element.
Element: oxygen, potassium Compound: sodium chloride, potassium dichromate Mixture: air, orange juice
Yes it is one of those things. It is an element.
Element.
Argon gas is an element. It will be element only. It can be part of some mixture. But never ever be a part of the compound. It is a noble gas.

Element.
IT IS A MIXTURE =] dumbo!
oxygen gas is a misture
Ar is the chemical symbol for the element argon. It is a noble gas and a pure element, not a compound or mixture.
Argon gas is an element. It will be element only. It can be part of some mixture. But never ever be a part of the compound. It is a noble gas.
No. It is a compound made of the elements oxygen and hydrogen: H2O.
Neither. The condensation of oxygen gas is a phase change. The oxygen itself would be an element, not a mixture.
