not a valid question
Nitrogen gas (N2) is not combined with other types of atoms. It exists as a diatomic molecule where two nitrogen atoms are bonded together covalently.
it depends on wht compound it its
Argon is an element. It is a noble gas that exists as individual atoms and is not chemically combined with other elements.
Ions
form covalent bond
The only way I can think of to get a mixture of separate atoms is to mix two noble gases--helium and argon, maybe. Any atom that doesn't have a full outer shell is going to create bonds with other atoms, and then you won't have "separate" atoms.
Argon gas is an element. It is a noble gas that exists as individual argon atoms and is not chemically combined with any other elements.
Yes, in two forms. Two identical Atoms bonded together [N2, H2, O2] are called Di-Atomic Molecules. OTHER THAN THIS, a Molecular Compound is ANY chemically bound collection of Different types of Atoms.
Each molecule of Carbon dioxide gas contains one atom of carbon combined with two atoms of Oxygen (CO2).
They form bonds with other atoms.
Anything that is not chemically combined but is in the same substance, i.e. oil in water, air (Nitrogen, Oxygen, Carbon Dioxide, Argon and other gases are not chemically combined.) and there are many more.
Nitrogen atoms do not spontaneously change into other kinds of atoms. However, in nuclear reactions or processes like radioactive decay, nitrogen atoms can be converted into different atoms.
