Valence electrons are the outermost electrons of an atom and are responsible for chemical bonding.<\/p>\n\n\n\n<p><strong>Magnesium (Mg)<\/strong> is in <strong>Group 2<\/strong> of the periodic table, which means it has <strong>two valence electrons<\/strong> in its neutral state. The electron configuration of neutral magnesium is:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mg (atomic number 12): 1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2<\/strong><\/li>\n<\/ul>\n\n\n\n<p>The two electrons in the <strong>3s orbital<\/strong> are the valence electrons.<\/p>\n\n\n\n<p>When magnesium forms an ion (Mg\u00b2\u207a), it <strong>loses both of its valence electrons<\/strong> to achieve a more stable electron configuration\u2014similar to that of a noble gas (neon, in this case). The resulting electron configuration of <strong>Mg\u00b2\u207a<\/strong> is:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>1s\u00b2 2s\u00b2 2p\u2076<\/strong><\/li>\n<\/ul>\n\n\n\n<p>This configuration represents a full octet, which is energetically favorable.<\/p>\n\n\n\n<p>Because Mg\u00b2\u207a has <strong>lost its two valence electrons<\/strong>, there are <strong>no dots<\/strong> in the Lewis diagram. Instead, we simply write <strong>[Mg]\u00b2\u207a<\/strong> to indicate the magnesium ion and its +2 charge. The absence of dots shows the loss of valence electrons.<\/p>\n\n\n\n<p>This is different from a neutral atom&#8217;s Lewis diagram, where dots represent the number of valence electrons. For example, a neutral Mg atom would be shown as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mg:<\/strong> with two dots: one on each side to represent the two valence electrons.<\/li>\n<\/ul>\n\n\n\n<p>In summary, <strong>Mg\u00b2\u207a<\/strong> does not have any valence electrons, so the correct Lewis dot diagram is just the element symbol in brackets with a <strong>2+<\/strong> charge:<br>\u2192 <strong>[Mg]\u00b2\u207a<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Draw the Lewis electron dot diagram for ion Mg2+; The correct answer and explanation is: Lewis Electron Dot Diagram for Mg\u00b2\u207a: The Lewis dot diagram for the Mg\u00b2\u207a ion is: [Mg]\u00b2\u207a \u2714 There are no dots around the element symbol because magnesium has lost its two valence electrons. 300-Word Explanation: The Lewis electron dot diagram [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-16349","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/16349","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=16349"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/16349\/revisions"}],"predecessor-version":[{"id":16350,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/16349\/revisions\/16350"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=16349"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=16349"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=16349"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
