Aluminum, a metal from group 13 of the periodic table, forms a cation with a <strong>+3 charge (Al\u00b3\u207a)<\/strong>. Chlorine, a nonmetal from group 17 (the halogens), gains one electron to form a <strong>\u22121 anion (Cl\u207b)<\/strong>.<\/p>\n\n\n\n<p>Each <strong>Al\u00b3\u207a<\/strong> ion contributes <strong>+3<\/strong> charge, and each <strong>Cl\u207b<\/strong> ion contributes <strong>\u22121<\/strong> charge. To balance the charges, we need <strong>three Cl\u207b ions<\/strong> for every <strong>one Al\u00b3\u207a ion<\/strong>, because:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Total positive charge from 1 Al\u00b3\u207a = +3<\/li>\n\n\n\n<li>Total negative charge from 3 Cl\u207b = 3 \u00d7 (\u22121) = \u22123<\/li>\n\n\n\n<li>Combined: +3 + (\u22123) = 0 \u2192 neutral compound<\/li>\n<\/ul>\n\n\n\n<p>Therefore, the correct ratio of aluminum to chlorine ions is <strong>1:3<\/strong>, and the empirical formula is written as <strong>AlCl\u2083<\/strong>.<\/p>\n\n\n\n<p>This compound is held together by <strong>ionic bonds<\/strong>, which are electrostatic attractions between oppositely charged ions. In solid aluminum chloride, these ions arrange themselves into a crystal lattice to maximize attraction and minimize repulsion, resulting in a stable structure.<\/p>\n\n\n\n<p>In aqueous solution or molten form, <strong>AlCl\u2083 dissociates<\/strong> into <strong>Al\u00b3\u207a<\/strong> and <strong>Cl\u207b<\/strong> ions, allowing it to conduct electricity, a characteristic of ionic compounds.<\/p>\n\n\n\n<p>It&#8217;s important not to write the formula as AlCl or AlCl\u2082, as these do not balance the charges correctly:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>AlCl: +3 \u2212 1 = +2 \u2192 not neutral<\/li>\n\n\n\n<li>AlCl\u2082: +3 \u2212 2 = +1 \u2192 not neutral<\/li>\n<\/ul>\n\n\n\n<p>Only <strong>AlCl\u2083<\/strong> gives a neutral compound, making it the correct ionic formula.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/05\/learnexams-banner5-60.jpeg\" alt=\"\" class=\"wp-image-220198\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Enter the correct ionic formula for the compound formed between the following.Al3+ and Cl\u2212Express your answer as a chemical formula.
