What is the systematic name for the compound made from zinc and sulfur?

The correct systematic name for the compound made from zinc and sulfur is indeed "zinc sulfide." This is named according to the rules of inorganic nomenclature which state that when naming binary compounds (compounds composed of two elements), the name of the metal is written first followed by the name of the non-metal, with the appropriate modifications.

In this case, zinc is a metal and sulfur is a non-metal. The non-metal sulfur is given the suffix "-ide" when it forms an ionic compound with a metal, resulting in "sulfide." Thus, the combination of zinc and sulfur yields "zinc sulfide."

Other choices incorporate different combinations of sulfur and zinc or other elements:

• "Zinc oxide" includes oxygen instead of sulfur.

• "Zinc sulfate" is a compound containing sulfur, but it is bonded with four oxygen atoms as well, which is a more complex compound typically represented as ZnSO₄.

• "Zinc sulfite" also involves sulfur but is a different compound that contains the sulfite ion (SO₃²⁻) instead of solely forming an ionic bond with the sulfide ion (S²⁻).

Therefore, the name "zinc sulfide" accurately reflects the chemical composition
