Gaseous Elements of Group 18
Abundant and Inert Gases
WEB noble gases are a group of seven chemical elements that belong to Group 18 (VIIIA) of the periodic table. These gases are known for their unique properties and are classified as noble gases due to their inert and unreactive nature. They include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive elements radon (Rn) and oganesson (Og).
Noble gases are characterized by their lack of chemical reactivity, which means they do not readily form compounds with other elements. This property is attributed to their electron configuration, which features a full outermost electron shell. Noble gases are colorless, odorless, and tasteless gases that occur naturally in the atmosphere and in certain geological formations.
Helium, the lightest noble gas, is the second most abundant element in the universe after hydrogen. It is used in a variety of applications, including balloons, airships, and cryogenic cooling. Neon is used in lighting applications, such as neon signs and fluorescent tubes. Argon is the third most abundant noble gas and is used as an inert shielding gas in welding and other industrial processes.
Krypton and xenon are used in various lighting applications, including high-intensity discharge lamps and lasers. Radon, a radioactive noble gas, is a natural component of the Earth's crust and can be released into the atmosphere during certain geological events. Oganesson, the heaviest noble gas, is a synthetic element that was first synthesized in 1999.
Noble gases are essential components of the universe and play important roles in various scientific and industrial applications. Their unique chemical properties make them valuable in a wide range of fields, from lighting to medicine and from aerospace to electronics.
