In 1898 Professors Ramsey and Travers found two more gases in the air, krypton and neon, and a little later still, there was found mixed with the krypton a further new gas, xenon.
What would Joseph Priestley, the discoverer of oxygen, and Cavendish, the discoverer of nitrogen, think could they step into the laboratory of Professor Ramsay and see test-tubes containing argon and helium and krypton and neon and zenon?
The majority of the krypton lines which Baly identifies with auroral lines require for their production a Leyden jar and spark gap.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "krypton" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: ammonia; gas; nitrogen; oxygen; silver
