Sulfur typically forms an anion with a 2\u2212 charge, as it gains two electrons to fill its valence shell, achieving a stable electron configuration. Thus, the charge on the sulfide ion (S\u00b2\u207b) is 2\u2212.<\/li>\n\n\n\n<li><strong>Copper Ion (Cu\u00b2\u207a)<\/strong>: Copper is a transition metal, and like other transition metals, it can form more than one type of ion. Copper typically forms two common oxidation states: +1 and +2. When copper forms a compound with sulfide (S\u00b2\u207b), the charge of the copper ion must balance out the charge of the sulfide ion.<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Since each sulfide ion carries a 2\u2212 charge, and there is one sulfide ion in CuS, the copper ion must have a charge of +2 to balance the overall charge of the compound.<\/li>\n\n\n\n<li>The compound must be electrically neutral, and the sum of the charges of the ions must equal zero. Therefore, to balance the \u22122 charge from the sulfide ion, the copper ion must carry a +2 charge.<\/li>\n<\/ul>\n\n\n\n<p>Thus, in CuS, the copper ion has a charge of <strong>+2<\/strong>, meaning its ionic charge is <strong>Cu\u00b2\u207a<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion:<\/h3>\n\n\n\n<p>The copper ion in CuS has a charge of <strong>+2<\/strong>, and the correct answer is <strong>A) 2+<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the ionic charge for the copper ion in CuS?
