To determine the correct chemical formula of an ionic compound, we must balance the total positive and negative charges so that the overall compound is electrically neutral.<\/p>\n\n\n\n<p>Zinc (Zn) is a transition metal, but it commonly forms only one stable ion: <strong>Zn\u00b2\u207a<\/strong>. This means zinc typically loses two electrons to achieve a stable electron configuration, forming a cation with a 2+ charge.<\/p>\n\n\n\n<p>Oxygen (O), on the other hand, is a nonmetal from group 16 of the periodic table. It typically gains two electrons to complete its octet, forming the <strong>oxide ion (O\u00b2\u207b)<\/strong>, which has a 2\u2212 charge.<\/p>\n\n\n\n<p>Now, when combining ions to form an ionic compound, the total positive charge must equal the total negative charge. In this case:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>One Zn\u00b2\u207a ion contributes a +2 charge.<\/li>\n\n\n\n<li>One O\u00b2\u207b ion contributes a \u22122 charge.<\/li>\n<\/ul>\n\n\n\n<p>Since the charges are equal in magnitude but opposite in sign, <strong>only one zinc ion and one oxide ion are needed<\/strong> to balance the charges. Therefore, the correct formula is <strong>ZnO<\/strong>, which reflects a 1:1 ratio of Zn\u00b2\u207a to O\u00b2\u207b ions.<\/p>\n\n\n\n<p>This formula follows the basic principles of ionic compound formation:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Identify the charges of the ions.<\/li>\n\n\n\n<li>Balance the total positive and negative charges.<\/li>\n\n\n\n<li>Write the formula with the lowest whole-number ratio of ions.<\/li>\n<\/ol>\n\n\n\n<p>Thus, zinc oxide is represented by the formula <strong>ZnO<\/strong>, indicating it is made up of one zinc ion and one oxide ion bonded together in an ionic lattice structure.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-345.jpeg\" alt=\"\" class=\"wp-image-232730\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Zinc oxide is formed from the (Zn\u00b2cation and the O\u00b2\u207banion.
