Krypton (atomic number 36, symbol Kr) is a chemical element and a tasteless, odorless, and colorless noble gas, which is inert. It is characterized by several spectral signatures or sharp emission lines, and the strongest of them are yellow and green.
Krypton has 30 isomers and unstable isotopes and 6 stable isotopes. One of them, Kr-81 occurs with other isotopes of the element and is created as a result of atmospheric reactions. Due to its radioactivity, the half-life of krypton-81 is 230,000 years. It has application in dating old ground water, but near surface water, the isotope is highly volatile....Read More
