Question

What type of chemical bond is primarily formed when zinc (a metal) reacts with sulfur (a nonmetal)?

Answer

An ionic bond. This occurs through the transfer of electrons from the metal to the nonmetal, forming oppositely charged ions.

Question

Why is the description "zinc and sulfur will share electrons" incorrect for this reaction?

Answer

Electron sharing defines covalent bonds, typical between two nonmetals. The large electronegativity difference between metal (Zn) and nonmetal (S) drives a complete electron transfer, not sharing.

Question

What specific ions are formed when zinc reacts with sulfur, and what are their charges?

Answer

Zinc loses two electrons to form the Zn²⁺ cation. Sulfur gains those two electrons to form the S²⁻ anion.

Question

What is the name and chemical formula of the compound produced in this reaction?

Answer

The compound is zinc sulfide, with the chemical formula ZnS.

Question

What is the driving force for zinc to transfer electrons to sulfur?

Answer

Both elements achieve stable electron configurations. Zinc loses 2e⁻ to resemble argon (stable octet), and sulfur gains 2e⁻ to complete its valence shell (octet), fulfilling the octet rule.
