Kryptonite: DC Comics: A radioactive crystal originating from the planet Krypton that is harmful to Kryptonians. Kryptonite comes in various colors with differing effects, and has been variously depicted as an element and compound. Kyber crystal: Star Wars: A rare, semi-sentient, crystalline material found across the galaxy.
A krypton-nitrogen bond is found in the cation [HC≡N–Kr–F] +, produced by the reaction of KrF 2 with [HC≡NH] + [AsF − 6] below −50 °C. [35] [36] HKrCN and HKrC≡CH (krypton hydride-cyanide and hydrokryptoacetylene) were reported to be stable up to 40 K. [27] Krypton hydride (Kr(H 2) 4) crystals can be grown at pressures above 5 ...
Jadarite's chemical formula is similar but not identical to the formula ("sodium lithium boron silicate hydroxide with fluorine") invented for the fictional substance kryptonite in the 2006 film Superman Returns. This coincidence attracted mass-media attention in 2007, shortly after jadarite's discovery. [21] [22] [23] [24]

[172] Gold kryptonite, for instance, nullifies Superman's powers but otherwise does not harm him. Kryptonite first appeared in a 1943 episode of the radio serial. [173]
There are 34 known isotopes of krypton (36 Kr) with atomic mass numbers from 67 to 103. Naturally occurring krypton is made of five stable isotopes and one (78 Kr) which is slightly radioactive with an extremely long half-life, plus traces of radioisotopes that are produced by cosmic rays in the atmosphere.
Martin, who has said he was present outside the Capitol during the siege, also represented two other people found guilty of taking part in the attempt to overturn Trump's 2020 election defeat.
Krypton is usually portrayed in comics as the home of a fantastically advanced civilization, which is destroyed when the planet explodes. As originally depicted, all the civilizations and races of Krypton perished in the explosion, with one exception: the baby Kal-El who was placed in an escape rocket by his father, Jor-El, and sent to the planet Earth, where he grew up to become Superman.
