To correctly determine the ions in an ionic compound, one must understand how to interpret chemical formulas and oxidation states.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>NaCl<\/strong> is composed of sodium (Na) and chlorine (Cl). Sodium loses one electron to form Na\u207a, and chlorine gains one to form Cl\u207b. Since both ions have charges of one in opposite directions, they combine in a 1:1 ratio.<\/li>\n\n\n\n<li><strong>CoCO\u2083<\/strong> contains cobalt and the carbonate polyatomic ion. CO\u2083\u00b2\u207b is a polyatomic ion with a 2\u207b charge. For the compound to be neutral, cobalt must provide a 2\u207a charge, forming Co\u00b2\u207a. Therefore, the ions are Co\u00b2\u207a and CO\u2083\u00b2\u207b. Note that the charge is written with the number first (2\u207a) according to standard notation.<\/li>\n\n\n\n<li><strong>NiSO\u2084<\/strong> involves nickel and the sulfate ion. SO\u2084\u00b2\u207b is the sulfate ion with a 2\u207b charge. To balance the charge, nickel must be Ni\u00b2\u207a. This pairing confirms the compound is electrically neutral.<\/li>\n\n\n\n<li><strong>CrS<\/strong> includes chromium and sulfur. Sulfide (S\u00b2\u207b) carries a 2\u207b charge. Therefore, chromium must be Cr\u00b2\u207a to balance the overall charge. This makes CrS a neutral ionic compound.<\/li>\n\n\n\n<li><strong>VBr\u2083<\/strong> is made up of vanadium and bromine. Each bromide ion is Br\u207b with a 1\u207b charge. Since there are three bromides, the total negative charge is 3\u207b. Therefore, vanadium must have a 3\u207a charge, written as V\u00b3\u207a, to create a neutral compound.<\/li>\n<\/ol>\n\n\n\n<p>In all cases, the total positive and negative charges must balance. It is important to follow naming conventions by writing the number before the sign in the ion symbols.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-133.jpeg\" alt=\"\" class=\"wp-image-26991\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-133.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-133-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-133-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Try Again Your answer is incorrect. \u2022 Compound CoCO3: Your answer is incorrect. \u2022 Compound NiSO4: Your answer is correct.
