Xenon is a colorless, odorless gas that belongs to the noble gases group in the periodic table. It has the atomic number 54 and is found in trace amounts in the Earth's atmosphere. Due to its low reactivity, xenon is often used in specialized applications, such as lighting and medical imaging. In lighting, xenon is used in high-intensity discharge lamps, which produce bright, white light. Additionally, it plays a role in MRI machines, where it can be used as a contrast agent. Its unique properties make xenon valuable in various scientific and industrial fields.
