What is the Stock system name for NiS?

Question

Quizplus · Accepted Answer

The Stock system name for NiS is nickel(II)sulfide because Ni has a fixed charge of +2 and S has a fixed charge of -2, hence, the roman numeral II is used to indicate the charge on the nickel ion. Choice A (nickel sulfide) is incorrect because it does not indicate the oxidation state of Ni. Choice C (nickel(II)sulfite) is incorrect because sulfite has a different chemical formula (SO3^2-) than sulfide (S^2-). Choice D (nickel(II)sulfate) is incorrect because sulfate has a different chemical formula (SO4^2-) than sulfide (S^2-). Therefore, the best choice is B, nickel(II)sulfide.
