The principal ones are carbon and nitrogen.
The elements that make covalent bonds are non-metal and non-metal chemicals
A non-metal and a non-metal form covalent bonds.
Carbon has the ability to make 4 strong covalent bonds with other elements or carbon atoms. Also it can make stable double, triple bonds with other atoms. Carbon can make long stable chains .
Covalent bonds are typically formed by the sharing of electrons between two atoms. Atoms with similar electronegativities tend to form covalent bonds. Covalent bonds can be made up of nonmetals or metalloids in a compound.
Covalent bonds do not "make up" anything; they merely hold the atoms that carry the mass of the substance together. If the questioner means, "How many covalent bonds are in a nitrogen molecule with formula N2" the answer is "one triple covalent bond."
A carbon atom can form single, double, or triple bonds with other atoms, typically with elements like hydrogen, oxygen, nitrogen, and other carbons. This flexibility allows for the vast diversity of organic molecules found in nature.
All non-metals in group IV will be able to form 4 covalent bonds with other elements. They need 4 more electrons to form the octet structure in their valence shell. Hence, they can form 4 single covalent bonds to constitute the covalent structure. On the other hand, elements in group III, such as boron, can also make 1 double bond and 3 single bonds to share 5 electrons to achieve octet structure.
Carbon can only make a triple bond with 1 atom.
The number of covalent bonds depends on the compound it makes. Xenon can make maximum of six covalent bond (as in XeF6) and minimum of 2 as in (XeF2).
it can make covalent bonds!
An atom of carbon typically makes four single bonds in a covalent molecule when there are no double or triple bonds. This tetravalency allows carbon to form stable molecules by sharing its four valence electrons with other atoms. Each bond involves the sharing of one electron from carbon and one from the other atom, resulting in a strong covalent bond.
Elements make covalent bonds to achieve a stable electronic configuration by sharing electrons with another element. This sharing allows both atoms to fill their outer electron shells and become more stable.
