The correct answer is Xenon.
Xenon is a chemical element with the symbol Xe and atomic number 54. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas at standard temperature and pressure. It occurs in the Earth’s atmosphere in trace amounts. Xenon is the second-most abundant noble gas in the Earth’s atmosphere, at 0.09%. It is more abundant in the atmospheres of Jupiter and Saturn, where it constitutes 0.15% and 0.08% of the atmosphere, respectively.
Xenon is a noble gas, which means that it is very stable and does not react with other elements. It is used in a variety of applications, including lighting, lasers, and medical imaging.
Neon, krypton, and argon are also noble gases, but
