Answer:

The correct option is: A carbon atom can complete its valence shell by forming four covalent bonds

Explanation:

Carbon is a chemical element that belongs to the group 14 of the periodic table. The atomic number of carbon atom is 6 and it is denoted by the chemical symbol C.

The electronic configuration of carbon is: 1s², 2s², 2p².  

Therefore, there are 2 electrons in the first electronic shell and 4 electrons in the second electronic shell of the carbon atom.  

<u>There are </u><u>four valence electrons </u><u>in a carbon atom and thus it can form four covalent bonds to complete its valence shell. Therefore, carbon atom is tetravalent.</u>
