It forms a cation with a +1 charge, denoted as <strong>K\u207a<\/strong>.<\/li>\n\n\n\n<li>Sulfur (S) is a nonmetal from Group 16. When it bonds with metals, it typically forms an anion with a -2 charge, written as <strong>S\u00b2\u207b<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Naming Ionic Compounds:<\/h3>\n\n\n\n<p>The general rule for naming ionic compounds is to name the cation first (in this case, potassium) and then the anion (sulfide in this case). For a simple ionic compound like K\u2082S, you follow these steps:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Cation Naming:<\/strong> The potassium ion is K\u207a. When potassium forms an ionic compound, it retains its name &#8220;potassium.&#8221;<\/li>\n\n\n\n<li><strong>Anion Naming:<\/strong> The sulfide ion is formed by sulfur, which has gained two electrons to form S\u00b2\u207b. The name of the anion is derived from the element&#8217;s root name, sulfur, and adding the suffix &#8220;-ide&#8221; to it. Hence, it becomes <strong>sulfide<\/strong>.<\/li>\n<\/ol>\n\n\n\n<p>The compound K\u2082S consists of two potassium ions (K\u207a) and one sulfide ion (S\u00b2\u207b). So, the name of the compound is <strong>potassium sulfide<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why Not the Other Options?<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A. Dipotassium sulfate<\/strong>: This name would apply to <strong>K\u2082SO\u2084<\/strong> (potassium sulfate), which is a different compound. Sulfate (SO\u2084\u00b2\u207b) involves a polyatomic ion, while sulfide (S\u00b2\u207b) is a simple ion.<\/li>\n\n\n\n<li><strong>B. Potassium bisulfide<\/strong>: This name would apply to a compound with a sulfide ion and a hydrogen ion (e.g., KHS), but this is not K\u2082S.<\/li>\n\n\n\n<li><strong>D. Potassium disulfide<\/strong>: This name would refer to a compound with two sulfur atoms, such as <strong>K\u2082S\u2082<\/strong>, which is not the case here.<\/li>\n<\/ul>\n\n\n\n<p>Thus, <strong>C. Potassium sulfide<\/strong> is the correct answer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The correct name for K2S is potassium sulfate A dipotassium sulfateB potassium bisulfideC potassium sulfideD potassium disulfide The correct answer and explanation is : The correct name for K\u2082S is Potassium sulfide.
