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.
Krypton-81 is useful in determining how old the water beneath the ground is. [10] Radioactive krypton-81 is the product of spallation reactions with cosmic rays striking gases present in the Earth atmosphere, along with the six stable or nearly stable krypton isotopes. [11] Krypton-81 has a half-life of about 229,000 years.
Krypton is used in some photographic flashes for high speed photography. Krypton gas is also combined with mercury to make luminous signs that glow with a bright greenish-blue light. [39] Krypton is mixed with argon in energy efficient fluorescent lamps, reducing the power consumption, but also reducing the light output and raising the cost. [40]
Kandor (commonly known as the Bottle City of Kandor) [1] is a fictional city spared from the doomed world of Krypton in DC Comics' Superman titles. Before Krypton exploded, the futuristic city was captured by the supervillain Brainiac , miniaturized by his shrinking ray and placed inside a glass bell jar.
Organokrypton chemistry describes the synthesis and properties of organokrypton compounds, chemical compounds containing a carbon to krypton chemical bond. Far fewer such compounds are known than organoxenon compounds. The first organokrypton compound, HKrCCH, was reported in 2003 and made by photolytic insertion of a krypton atom into ...
Krypton-85 (85 Kr) is a radioisotope of krypton.. Krypton-85 has a half-life of 10.756 years and a maximum decay energy of 687 keV. [1] It decays into stable rubidium-85.Its most common decay (99.57%) is by beta particle emission with a maximum energy of 687 keV and an average energy of 251 keV.
The current model of the nucleus in 1934 was the liquid drop model first proposed by George Gamow in 1930. [53] His simple and elegant model was refined and developed by Carl Friedrich von Weizsäcker and, after the discovery of the neutron, by Werner Heisenberg in 1935 and Niels Bohr in 1936. It agreed closely with observations.
