Answer: A) Nonmetal carbon shares valence electrons with each nonmetal chlorine forming four covalent bonds.
Explanation: Carbon has atomic no 6. It has 4 valence electrons. It can only share electrons as it is difficult to gain or lose 4 electrons to complete it's octet.
Chlorine has atomic no 17 . It has 7 valence electrons and need one electron to complete its octet.
Thus carbon will share 4 electrons, one each with four chlorine atoms to form carbon tetra chloride.
Covalent bond is formed by sharing of electrons whereas Ionic bond is formed by transfer of electrons between atoms.
