Xenon is a colorless, odorless gas that belongs to the group of elements known as noble gases. It is found in trace amounts in the Earth's atmosphere and is used in various applications, such as lighting and photography. When electricity passes through xenon gas, it produces a bright blue light, making it popular for high-intensity discharge lamps and flash photography. This element is represented by the symbol Xe on the periodic table and has an atomic number of 54. Xenon is unique because it can form compounds with other elements, unlike most noble gases. Its rarity and special properties make it valuable in scientific research and technology.
