F and Cl are extremely electronegative elements and tend to form F- and Cl- ions easily. In other words, they will form compounds only when they can polarize the electron cloud towards them, i.e, cause …
WebHelium, neon, argon, krypton and xenon are in Group 0. They all have a full outer electron shell which means they are already stable and so do not need to lose or gain electrons. WebBoth helium and neon are used as cryogenic refrigerants. Xenon is an anesthetic, albeit a costly one. Radon is a product of the radioactive decomposition of radium compounds. Noble gases are often used in fluorescent lighting and discharge lamps. This is because they easily emit electromagnetic radiation.
WebBecause light helium group gases (such as helium and neon) have little or no anesthetic ability to human body, they can be used to replace nitrogen to prepare breathing mixture … WebHelium has only 2 2 6 protons, while neon has 10.
