Some examples of heavy metals include lead, mercury, and arsenic.<\/p>\n<p>Noble gases are elements that are very stable and do not react with other elements. They are all gases at room temperature and have very low reactivity. Some examples of noble gases include helium, neon, argon, krypton, and xenon.<\/p>\n<p>Light metals are elements that are relatively low in atomic mass and have a low density. They are often soft and malleable. Some examples of light metals include lithium, sodium, potassium, and magnesium.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>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":[19],"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>The elements with atomic numbers 9, 17, 35, 53, 85 are all A.
