The number of <strong>protons<\/strong> determines the element. The element with <strong>16 protons<\/strong> is <strong>sulfur (S)<\/strong>. The number of <strong>neutrons<\/strong> affects the <strong>mass number<\/strong>, and the number of <strong>electrons<\/strong> affects the <strong>charge<\/strong> of the atom.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Step-by-step Analysis:<\/h4>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>First Ion:<\/strong><ul><li>Protons: 16 (so the element is sulfur)<\/li><li>Neutrons: 18<\/li><li>Electrons: 18<br>The mass number is the sum of protons and neutrons:<br>16+18=3416 + 18 = 3416+18=34<br>The charge is calculated by comparing protons and electrons:<br>16\u221218=\u2212216 &#8211; 18 = -216\u221218=\u22122<br>So, the ion has a 2\u207b charge.<\/li><\/ul>Therefore, the symbol is:<br><strong>\u00b3\u2074S\u00b2\u207b<\/strong><\/li>\n\n\n\n<li><strong>Second Ion:<\/strong><ul><li>Protons: 16 (element is still sulfur)<\/li><li>Neutrons: 16<\/li><li>Electrons: 18<br>The mass number is:<br>16+16=3216 + 16 = 3216+16=32<br>The charge is again:<br>16\u221218=\u2212216 &#8211; 18 = -216\u221218=\u22122<\/li><\/ul>So, the ion symbol is:<br><strong>\u00b3\u00b2S\u00b2\u207b<\/strong><\/li>\n<\/ol>\n\n\n\n<h4 class=\"wp-block-heading\">Summary:<\/h4>\n\n\n\n<p>These are isotopes of sulfur because they have the same number of protons but different numbers of neutrons. They are also <strong>ions<\/strong> because they have more electrons than protons, which results in a negative charge. A sulfur ion with two extra electrons is commonly found as <strong>S\u00b2\u207b<\/strong>, particularly in compounds such as sulfides (e.g., FeS or H\u2082S). The notation helps identify both the specific isotope and the electrical charge of the particle.<\/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-banner8-1093.jpeg\" alt=\"\" class=\"wp-image-238832\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is the symbol of an ion with 16 protons, 18 neutrons, and 18 electrons?
