Therefore, the <a href=\"https:\/\/valenceelectrons.com\/valence-electrons-of-argon\/\">valence electrons of argon<\/a> are eight. The ability of an atom of an element to join another atom during the formation of a molecule is called valency(valence).<\/p>\n\n\n\n<p>The number of unpaired electrons in the last orbit of an element is the valency of that element. The electron configuration of argon shows that the argon atom has no unpaired electrons. Therefore, the valency of the argon atom is 0.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-is-argon-ar-an-inert-gas\">Why is argon an inert gas?<\/h2>\n\n\n\n<p>The elements in group-18 of the periodic table are inert gases. The inert gases of Group-18 are&nbsp;<a href=\"https:\/\/valenceelectrons.com\/helium-electron-configuration\/\">helium(He)<\/a>,&nbsp;<a href=\"https:\/\/valenceelectrons.com\/neon-electron-configuration\/\">neon(Ne)<\/a>, argon(Ar), <a href=\"https:\/\/valenceelectrons.com\/krypton-electron-configuration\/\">krypton(Kr)<\/a>, <a href=\"https:\/\/valenceelectrons.com\/xenon-electron-configuration\/\">xenon(Xe)<\/a>, and <a href=\"https:\/\/valenceelectrons.com\/radon-electron-configuration\/\">radon(Rn)<\/a>. We know that the element in group-18 is argon.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"922\" height=\"340\" src=\"https:\/\/valenceelectrons.com\/wp-content\/uploads\/2021\/12\/Position-of-argonAr.jpg\" alt=\"Position of argon\" class=\"wp-image-3998\" srcset=\"https:\/\/valenceelectrons.com\/wp-content\/uploads\/2021\/12\/Position-of-argonAr.jpg 922w, https:\/\/valenceelectrons.com\/wp-content\/uploads\/2021\/12\/Position-of-argonAr-300x111.jpg 300w, https:\/\/valenceelectrons.com\/wp-content\/uploads\/2021\/12\/Position-of-argonAr-768x283.jpg 768w\" sizes=\"(max-width: 922px) 100vw, 922px\" \/><figcaption class=\"wp-element-caption\">Position of argon<\/figcaption><\/figure><\/div>\n\n\n<p>The electron configuration of argon shows that the orbit at the end of argon is filled with electrons. Argon does not want to exchange or share any electrons because the last orbit of argon is full of electrons.<\/p>\n\n\n\n<p>And argon does not form any compounds because it does not share any electrons. They do not participate in chemical bonding and chemical reactions. For this, they are called inert elements.<\/p>\n\n\n\n<p>The inert elements are in the form of gases at normal temperatures. For this inert elements are called inert gases. Again for this same reason, inert gas is called a noble gas.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"faqs\">FAQs<\/h2>\n\n\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<ol class=\"rank-math-list \">\n<li id=\"faq-question-1678954140910\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What is the symbol for argon?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The symbol for argon is \u2018Ar\u2019.<\/p>\n\n<\/div>\n<\/li>\n<li id=\"faq-question-1678954152118\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">How many electrons does argon have?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>18 electrons.<\/p>\n\n<\/div>\n<\/li>\n<li id=\"faq-question-1678954168920\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">How do you write the full electron configuration for argon?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>1s<sup>2<\/sup> 2s<sup>2<\/sup> 2p<sup>6<\/sup> 3s<sup>2<\/sup>\u00a03p<sup>6<\/sup>.<\/p>\n\n<\/div>\n<\/li>\n<li id=\"faq-question-1678954193592\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">How many <a href=\"https:\/\/valenceelectrons.com\/what-are-valence-electrons\/\">valence electrons<\/a> does argon have?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Eight valence electrons.<\/p>\n\n<\/div>\n<\/li>\n<li id=\"faq-question-1678954203311\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What is the valency of argon?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The valency of argon is 0.<\/p>\n\n<\/div>\n<\/li>\n<\/ol>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Argon is the 18th element in the periodic table and its symbol is \u2018Ar\u2019.
