Inert gases are gases that do not react with other elements. This is because they have a full outer shell of electrons. Helium&#8217;s two electrons are paired, which means that they have opposite spins. This makes it difficult for other atoms to interact with helium&#8217;s electrons.<\/p>\n<p>Argon, neon, and krypton are also inert gases, but they have eight electrons in their outer shells. This means that they are more stable than helium and are less likely to react with other elements.<\/p>\n<p>Helium is the only inert gas that has only two electrons in its outer shell. This makes it unique and special.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[636],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Which of the following inert gas has only two electrons in its outer most cell?
