Oxygen gas is an element.
In the atmosphere is is a diatomic molecule ( O2 ; O=O).
It also forms a triatomic molecule , ozone (O3), found in the upper atmosphere.
It is part of a mixture of gases in the atmosphere. The others being nitrogen, and minute amounts of carbon dioxide, water vapour , the noble gases, methane, sulphur dioxide.
It does NOT form a compound in the atmosphere. However, it does form a compound with many metals as their oxides. e.g. Iron oxide (Fe2O3).
Element: oxygen, potassium Compound: sodium chloride, potassium dichromate Mixture: air, orange juice
Yes it is one of those things. It is an element.
Ar is the chemical symbol for the element argon. It is a noble gas and a pure element, not a compound or mixture.
Ammonia (NH3) is a compound, not an element. It is a homogeneous mixture when dissolved in water, but a pure sample of ammonia gas is considered a compound.
Xenon gas is an element. It is a noble gas found on the periodic table with the atomic number 54.
