A compound is simply different elements bonded to each other, in this case tin (Sn) and two fluorine atoms (F).
fluorine is a gas, an element not a mixture. It is in the periodical table as well.
Fluorine gas is an element
Fluorine is an element; its atomic number is 9.
Ionically bonded compound.
It's is a compound, not a mixture
Compound
No such substance as 'sodium chlorine'. I think you mean 'sodium chloride'. I which case it is an ionic compound. Separately , sodium(metal) is an element and chlorine(gas) is an element. They both appear in the Periodic Table. 'Mixture', does not come into question.
Two fluorine atoms can not form a compound they simply form a [molecule]
Nitrogen is an element . Nitrogen gas, however, is often called nitrogen and is a molecule consisting of two nitrogen atoms bound together. Thus it may be considered to be a compound.
Pure water vapor is a compound, just as liquid water is.
The answer is Fluorine!Argon, one of the noble gases.
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.
Natural gas is a 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.
