In acetonitrile (C\u2082H\u2083N), nitrogen forms a <strong>triple bond<\/strong> with a carbon atom, so <strong>3 of those electrons are bonding<\/strong>. The <strong>remaining 2 electrons form a nonbonding pair<\/strong>, commonly known as a lone pair.<\/p>\n\n\n\n<p>Here is the Lewis structure for acetonitrile:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>  H   H   H\n   |   |   |\nH\u2013C\u2013C\u2261N:\n<\/code><\/pre>\n\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n\n<p>To draw the Lewis Electron-Dot structure for acetonitrile, we start by identifying the atoms and their bonding preferences. The molecular formula C\u2082H\u2083N tells us there are two carbon atoms, three hydrogen atoms, and one nitrogen atom. Carbon has 4 valence electrons, hydrogen has 1, and nitrogen has 5. The total number of valence electrons is:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carbon: 2 \u00d7 4 = 8<\/li>\n\n\n\n<li>Hydrogen: 3 \u00d7 1 = 3<\/li>\n\n\n\n<li>Nitrogen: 5<\/li>\n\n\n\n<li><strong>Total: 8 + 3 + 5 = 16 valence electrons<\/strong><\/li>\n<\/ul>\n\n\n\n<p>The structure begins with a carbon (C) bonded to three hydrogen (H) atoms, forming a methyl group. This carbon is then single bonded to another carbon atom, which is in turn <strong>triple bonded<\/strong> to a nitrogen atom. Each hydrogen forms a single bond with the carbon, using one electron pair each.<\/p>\n\n\n\n<p>The triple bond between the second carbon and nitrogen consists of three shared electron pairs. With three bonding pairs used by nitrogen, the <strong>remaining pair is nonbonding<\/strong>, completing its octet. This lone pair sits on nitrogen and is not involved in bonding.<\/p>\n\n\n\n<p>This configuration satisfies the octet rule for all atoms. The methyl carbon is surrounded by eight electrons from its three H\u2013C bonds and its C\u2013C bond. The second carbon has one single bond to the methyl carbon and three bonding pairs with nitrogen, also totaling eight electrons.<\/p>\n\n\n\n<p>Understanding how nitrogen distributes its valence electrons illustrates how molecules achieve stability through bonding and lone pairs.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"722\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-175.jpeg\" alt=\"\" class=\"wp-image-29951\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-175.jpeg 722w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-175-212x300.jpeg 212w\" sizes=\"auto, (max-width: 722px) 100vw, 722px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>How many valence electrons does a nitrogen atom have?
