History

History
The element Krypton was discovered by William Ramsay in year 1898 in United Kingdom. Krypton derived its name from from the Greek kryptos, meaning 'hidden'
The element Radon was discovered by Friedrich Ernst Dorn in year 1900 in Germany. Radon derived its name derived its name from From radium, as it was first detected as an emission from radium during radioactive decay
