neon and helium
Yes, The elements hydrogen, nitrogen, oxygen, and sulfur are all molecular elements that exist in nature. Due to their reactivity, it is rare to find the halogens and phosphorus in their elemental forms in nature.
Numerous elements exist as diatomic molecules in nature, including hydrogen, oxygen, nitrogen, chlorine, bromine, fluorine, and iodine.
Ozone exists as triatomic molecules. O3
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.
Hydrogen, nitrogen, oxygen, and the hallogens.
Yes: Oxygen and nitrogen are the most frequently encountered examples.

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.
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.
No, blue trees do not exist in nature.
No, sodium and mercury exist as diatomic molecules in the vapour state due to the nature of their chemical bonding. Sodium forms Na2 while mercury forms Hg2 molecules.
molecules
forces exist in nature
No, there are no bugs with red blood that exist in nature.
The were not invented, they exist. Atoms and molecules were discovered.
All alkali metals exist in nature as compounds.
The chemical substances found in the atmosphere exist as gases.
