This element is carbon.
covalent bonds
Rule of thumb answer is covalent bonds form between non metal elements.
Aluminium will form covalent bonds with other elements if the difference in the electronegativities between the two elements are below 1.7
Why does group 4A elements tend to form covalent bonds rather than ionic bonds? 
The elements carbon and hydrogen both form primarily covalent bonds.

A non-metal and a non-metal form covalent bonds.
The elements carbon and hydrogen both form primarily covalent bonds.
not more than three !
Covalent or molecular compounds form when elements share electrons in a covalent bond to create molecules.
Elements with intermediate electronegativities, such as carbon and hydrogen.
Group-14 elements share electrons. they form covalent bonds.
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.
Covalent bonds usually form between two nonmetals/
