What are the naturally occurring isotopes?
Hydrogen and its two naturally occurring isotopes, deuterium and tritium. All three have the same number of protons (labeled p+) but different numbers of neutrons (labeled n). A family of people often consists of related but not identical individuals.
Is krypton naturally occurring?
Krypton is produced deep within stars during nucleosynthesis . It has six naturally occurring (i.e., stable) isotopes , the most abundant of which is krypton-84 (57%). Some long-lived radioactive isotopes exist as well.
What is the natural state of krypton?
gas
Krypton is a gas with no colour or smell. It does not react with anything except fluorine gas.

Krypton/Atomic number
Krypton (Kr). Diagram of the nuclear composition and electron configuration of an atom of krypton-84 (atomic number: 36), the most common isotope of this element. The nucleus consists of 36 protons (red) and 48 neutrons (yelow).
How many natural isotopes occur in nature?
Scientists estimate that the elements that occur naturally on Earth (some only as radioisotopes) occur as 339 isotopes (nuclides) in total. Only 252 of these naturally occurring nuclides are stable in the sense of never having been observed to decay as of the present time.

What minerals is krypton found in?
There are no krypton-bearing minerals. It is obtained from liquefying air, where it occurs about 1 part per million.
What is the most common isotope of krypton?
Naturally occurring krypton is a mixture of six isotopes and they are found in the percentages shown: 78Kr (0.4%), 80Kr (2.3%), 82Kr (11.6%), 83Kr (11.5%), 84Kr (57.0%) and 86Kr (17.3%). The most abundant isotope is 84Kr at 57.0%.
What are the isotopes of krypton used for?
Krypton isotopes are used in various medical and scientific applications. Kr-82 is used for the production of Rb-81/Kr-81m generators. Many of the stable isotopes of Krypton are used in the study of the pulmonary system.

Are there important isotopes in Krypton?
There are 33 known isotopes of krypton (36Kr) with atomic mass numbers from 69 through 101. 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.
Is the Krypton element stable or unstable?
Naturally occurring krypton in Earth’s atmosphere is composed of five stable isotopes, plus one isotope (78 Kr) with such a long half-life (9.2×10 21 years) that it can be considered stable . (This isotope has the second-longest known half-life among all isotopes for which decay has been observed; it undergoes double electron capture to 78 Se).
