Generally speaking none .These are the inert gases, with either full outer shells (He and Ne which have no known compounds) or an ns2 np6 outer octet configuration.
There are some compounds known for the heavier members of the group particularly Xenon . This has compounds such as XeCl2, XeF4, XeO3, XeO4
So 2, 4, 6 or 8 covalent bonds for Xe!
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.
When covalent bonds are formed between atoms, they become more stabilized than the individual atoms summed altogether.
Carbon is in Group V. Thus, it needs 4 more electrons so as to achieve the octet structure in its valence shell. As such, carbon has make at most 4 single covalent bonds. The least number of covalent bonds carbon can make is 2 double bonds. We do not see an example of carbon forming 1 covalent bond involving the sharing of all 4 of its valence electrons.
Carbon is tetra-valent meaning it can form 4 covalent bonds
Covalent bonds involve sharing of electrons.
The elements that make covalent bonds are non-metal and non-metal chemicals
A non-metal and a non-metal form covalent bonds.

The principal ones are carbon and nitrogen.

it can make covalent bonds!

It would form an ionic bond. The atom with 7 electrons is cation and the atom with 1 is an anion.
Sub atomic articles cannot make covalent bonds as atoms do.
Carbon typically forms covalent bonds. It is rare for it to form ionic bonds.
metallic, ionic, and covalent bonds
A covalent bond does not have oxygen in it but ionic bonds do and because Boron cannot join with oxygen it can only make covalent bonds hope that helps =)
