There are two forms of allotropes of carbon amorphous and crystalline.
Covalent bonds are always formed by the sharing of electrons between two atoms.
Carbon always forms covlent bonds as it can niether lose 4 electrons as it would require a lot of energy to remove 4 electrons leaving behind the nucleus with 6 protons nor it can gain 4 electrons as it will be difficult for the nucleus with 6 protons to hold on to 10 electrons.
Valence electrons is the number of electrons in the outermost cell of an atom.
As the number of valence electrons in the nitrogen is 5 so in order to complete octet it shares three of its electrons with another nitogen to form triple bonds.
Hydrogen shares its only outermost electron with another Hydrogen to form covalent bonds.
Think about the electron-sharing behavior of these elements.
