This means copper has lost two electrons, resulting in a 2+ charge.<\/li>\n\n\n\n<li><strong>Nitrate Ion (NO\u2083\u207b)<\/strong>: The nitrate ion is a polyatomic ion consisting of one nitrogen atom (N) bonded to three oxygen atoms (O), with an overall charge of 1-. The nitrate ion is commonly represented as NO\u2083\u207b.<\/li>\n\n\n\n<li><strong>Balancing Charges<\/strong>: In order to form a neutral compound, the total positive charge must balance the total negative charge. Since the copper ion has a +2 charge (Cu\u00b2\u207a) and each nitrate ion has a -1 charge (NO\u2083\u207b), two nitrate ions are needed to balance the +2 charge from the copper ion.<\/li>\n\n\n\n<li><strong>Combining the Ions<\/strong>: To balance the charges, two nitrate ions are required for each copper ion. Therefore, the formula for Copper (II) nitrate becomes <strong>Cu(NO\u2083)\u2082<\/strong>, indicating one copper ion (Cu\u00b2\u207a) paired with two nitrate ions (NO\u2083\u207b).<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Key Points:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The (II) in Copper (II) nitrate indicates the +2 oxidation state of the copper ion.<\/li>\n\n\n\n<li>Nitrate, as a polyatomic ion, always retains its -1 charge.<\/li>\n\n\n\n<li>The formula reflects the need for two nitrate ions to balance the charge of one Cu\u00b2\u207a ion.<\/li>\n<\/ul>\n\n\n\n<p>This is a typical ionic compound where a metal cation (Cu\u00b2\u207a) pairs with an anion (NO\u2083\u207b) to form a stable neutral compound.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-515.jpeg\" alt=\"\" class=\"wp-image-255879\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is the chemical formula for Copper (II) nitrate?
