Final answer:
A compound made from carbon and sulfur would be a covalent compound, as these elements are both nonmetals that share electrons when they bond. Therefore correct option is D
Step-by-step explanation:
A neutral compound made by the elements carbon and sulfur would be a covalent compound. Both carbon and sulfur are nonmetals and when they react with one another, the atoms share electrons to form a covalent bond. Ionic compounds, on the other hand, are typically formed between metals and nonmetals where there’s a transfer of electrons resulting in cations and anions that create an electrically neutral substance. Since carbon and sulfur do not fit into this scenario of metal to nonmetal reaction, they do not form an ionic compound. Furthermore, neither carbon nor sulfur are transition metals, and this compound is not a cation as it is neutral and contains no positively charged ions alone.
