It is found in nature in its pure form (not as a compound).
Cultural, biological, physical, and chemical.
The number of protons, which are found in the nucleus of an atom.
Sugars, lipids [both fats and oils], proteins, hormones, and nucleic acids are the main ones.
The main element in coal is carbon.
the main element found in the atmosphere of a gas giant is hydrogen, with some traces of helium.
Hydrogen.
The main building block for plastics is not an element but rather a molecule that's called 'monomere' which turns into a 'polymere' by combining many molecules together (polymerisation reaction) in plastics
silicon has 14 valence electrons, and therefore can form 14 covalent bonds. carbon is a main biological element (all living things are made of carbon-based compounds), silicon could be a candidate as a central biological element too because of the amount of electrons it has, would allow it to bond with many different elemements

It is found in nature in its pure form (not as a compound).
Tungsten is the main one. There may be others.
