Xenon is used as a starter gas in metal halide lamps for automotive HID headlights, and high-end "tactical" flashlights. The individual cells in a plasma display contain a mixture of xenon and neon ionized with electrodes.

May 22, 2020 · Xenon is a rare gas in the Earth’s atmosphere, present at a concentration of about 1 part per 11.5 million (0.087 parts per million). Although it’s rare, the best source of the element is extraction from liquid air.

Nov 9, 2019 · Ionized xenon gas is blue-violet, while the usual gas and liquid are colorless. One of xenon's uses is for ion drive propulsion. NASA's Xenon Ion Drive engine fires a small number of xenon ions at high speed (146,000 km/hour for the Deep Space 1 probe).

Feb 28, 2025 · Xenon, chemical element, a heavy and extremely rare gas of Group 18 (noble gases) of the periodic table. It was the first noble gas found to form true chemical compounds. More than 4.5 times heavier than air, xenon is colorless, odorless, and tasteless.

Aug 1, 2024 · When ionized, xenon emits a very bright and intense light. This is due to the fact that xenon gas can produce a broad spectrum of visible light, including a significant amount of ultraviolet (UV) light. This also makes it possible to use xenon light sources for UV laser systems.

Of the stable noble gases, xenon has the lowest ionization energy, which means that it most readily ionizes and produces light. Additionally, xenon has the lowest thermal conductivity, which means that the lamp emits less heat while in operation, saving energy.

Jul 28, 2023 · Xenon is a monatomic gas composed of single xenon atoms, meaning it has an atomic weight of 131.3 g/mol and an atomic radius of 108 pm. Its electronegativity is very low, at 1.1, and its ionization energy is 1170 kJ/mol.

May 5, 2024 · Xenon, a noble gas with atomic number 54, has a stable atomic structure with a full valence shell, rendering it innocuous under normal conditions (Bartik et al., 1998). This inertness is due to its high ionization energy and electron affinity, which result in low reactivity with other elements (Peng et al., 2016).

Ion Thrusters: Xenon gas is ionized and accelerated by electric fields to generate thrust in ion propulsion systems. This technology is used in some spacecraft to achieve efficient and prolonged propulsion.
