Word Nuance & Usage

Do not confuse krypton, the real chemical element and noble gas, with 'kryptonite,' the fictional radioactive mineral from the Superman comic books (which is said to originate from the fictional planet Krypton).

Coined in 1898 by British chemists Sir William Ramsay and Morris Travers from Ancient Greek 'krypton,' the neuter singular of 'kryptos' meaning 'hidden,' because the trace gas was concealed within liquid air.
