Any molecule can exist as either:
A Gas, a substance expanding occupy the space it is in and having no particular shape,
A liquid, a substance not expanding, but reshaping to occupy the space it is in, and having no shape,
A solid, a substance not adapting to the space it occupies in any way, and having a definite shape.
A molecule can exist as a single unit or part of a larger structure, such as a polymer. It can also exist in various states, including solid, liquid, or gas, depending on the conditions like temperature and pressure. Additionally, molecules can exist in different forms or isomers with the same chemical formula but different arrangements of atoms.

Ne
Yes, NO2 exists as a molecule. It is a reddish-brown gas composed of nitrogen and oxygen atoms in a 1:2 ratio.
Any molecule that contains hydrogen and carbon is an organic compound. If the molecule contains no other elements, it is also a hydrocarbon.

element
0.256 molecule of anything does not exist. The smallest representation of any compound is 1 molecule. If you mean 0.256 mole then: 0.256 mole x (18 g / mole) = 4.608 grams
It is only an atom.
molecule
The molecule of methane is more stable, carbon is tetravalent.
Hydrogen molecules do exist but they are less stable than hydrogen atoms. This is because hydrogen molecules require a large amount of energy to form since hydrogen atoms are highly reactive and tend to exist independently. Additionally, hydrogen molecules can easily dissociate into individual atoms at lower temperatures.
A molecule of an element is a molecule made up of the same substance that can exist as an atom; for example, oxygen as O2.
