Sulphur exists in two common allotropes: rhombic sulphur and monoclinic sulphur. Rhombic sulphur is a yellow, crystalline solid with a rhombic crystal structure. Monoclinic sulphur is a yellow, crystalline solid with a monoclinic crystal structure. Phosphorus exists in four common allotropes: white phosphorus, red phosphorus, black phosphorus, and violet phosphorus. White phosphorus is a waxy, white solid that is highly flammable. Red phosphorus is a red, amorphous solid that is less flammable than white phosphorus. Black phosphorus is a black, crystalline solid that is very stable. Bromine is a red-brown, liquid non-metal that is highly corrosive.<\/p>\n<p>In conclusion, the only non-metal that shows allotropy in the liquid state is carbon.<\/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 one of the following non-metals shows allotropy in the liquid state?
