• It's so sad that i only have one friend. But that's ok! We stick together like covalent bonds!

• I was discovered by Sir William Ramsay in 1898, in Great Britain.

• He and his students discovered me floating in the air after an experiment of boiling away water, oxygen, nitrogen, helium, and argon

• They decided to name me Krypton after the Greek word "kryptos" meaning "hidden" (because i was almost undetectable in the air during the experiment.

• I even helped William Ramsay discover Neon through this method.

• The famous cartoon, Superman and his weakness(Kryptonite) is based off of me.

• used with argon as a low-pressure filling gas for fluorescent lights

• used in some photographic flash lamps for high-speed photography, lamps
