Pure substances do not exist in nature because they always want to either gain or lose electrons to form a complete outer shell. Because of this they are almost always found as part of compounds with other elements. The exceptions are the noble gases which have complete outer shells naturally and are the most un-reactive elements, even so they are very hard to extract because of their low reactivity so it took years for scientists to even realise they existed because they wouldn't react with anything.

Why does hydrogen molecule does not exist?
Hydrogen molecules do exist (as H2); this is how hydrogen is found in nature.
Why ethanol called universal solvent?
Ethanol is a universal solvent as it contains both polar nature (OH) ion and the ethyl group which is a non polar substance. As a result it means that both polar nature molecules and non polar nature molecules can bond with ethanol which can as well form hydrogen bonding amongst substances.
Are molecules in cool substances closer together than in hot substances?
Yes, they are. Molecules get further apart as they gain energy.
What are the special proteins that can break large molecules into small molecules?
These substances are called enzymes.
Do all diatomic substances have covalent bonds?
All diatomic substances have covalent bonds even diatomic metal molecules such as sodium molecules (>2000 K).
What do not exist as molecules in nature?
neon and helium
Why does hydrogen molecule does not exist?
Hydrogen molecules do exist (as H2); this is how hydrogen is found in nature.
Many elements found in nature exist as?
The chemical substances found in the atmosphere exist as gases.
How do noble gases exist in nature?
Noble gasses exist in elemental form as individual atoms rather than molecules.
Do some elements in nature exist as molecules?
Yes: Oxygen and nitrogen are the most frequently encountered examples.
How does hydrogen get in to the body?
Hydrogen molecules don't exist by themselves in nature. Hydrogen gas is abundant throughout existence and you get it through water and air. Technically speaking, you are made up of hydrogen and carbon as well as countless other substances. It's EVERYWHERE
What are facts about halogens?
not found free in nature they exist as separate diatomic molecules they produce salts known as halides
Which atom exists as a diatomic molecule in nature?
Numerous elements exist as diatomic molecules in nature, including hydrogen, oxygen, nitrogen, chlorine, bromine, fluorine, and iodine.
Why do inert elements exist as mono atoms in molecules?
Inert elements are those elements whose valency is 0 therefore they are very less reactive in nature, they do not tend to form chemical bonds and therefore they exist as mono atoms in molecules.
What is the nature of the substances dissolved in water?
Substances that dissolve in water are polar molecules, like water. Also, many ionic compounds can also dissolve in water as well, such as common table salt, NaCl.
Are poler substances attracted to the other poler substances or to the nonpoler substances?
Polar molecules are attracted to other polar molecules with an opposite charge.
What is a attraction between molecules of different substances?
Adhesive forces are the attraction between molecules of different substances. This differs from cohesive forces which is attraction between same substances.
