Final answer:
Carbon tetrachloride (CCl4) is characterized by covalent bonding because it involves the sharing of electrons between non-metal elements - carbon and chlorine.
Step-by-step explanation:
Carbon tetrachloride (CCl4) is a compound composed of a carbon atom and four chlorine atoms. The bonding between the atoms in this molecule is covalent, as it involves the sharing of electrons between non-metal elements. Carbon and chlorine are both non-metals, and according to the periodic table, when non-metals bond together, the result is typically a covalent bond rather than an ionic bond. Therefore, carbon tetrachloride is characterized by covalent bonding.
