KryptonIn 1898, Morris William Travers, an English chemist, while working with Sir Willam Ramsay in London, discovered the element krypton. The name derives from the Greek word for “hidden.” It was a fraction separated from liquified air, which when placed in a Plücker tube connected to an induction coil yielded a spectrum with a bright yellow line with a greener tint than the known helium line and a brilliant green line that corresponded to nothing seen before. |
