Isotopes of xenon Isotopes of xenon. Naturally occurring xenon (54Xe) is made of eight stable isotopes and one very long-lived isotope. (124Xe, 126Xe, and 134Xe are predicted to undergo double beta decay, but this has never been observed in these isotopes, so they are considered to be stable.) Xenon has the second highest number of stable isotopes.

- One proton makes a hydrogen atom. The difference between isotopes is the number of neutrons bound to that proton. There are six known hydrogen isotopes, ranging from H-1 to H-6. The H-4 isotope has a range of half-life values, depending on the overall energy of the nucleus and its total angular momentum quantum number.

isotope An isotope is a form of a chemical element whose atomic nucleus contains a specific number of neutron s, in addition to the number of proton s that uniquely defines the element.The nuclei of most atom s contain neutrons as well as protons.n atom of carbon-14 contains 6 protons and 8 neutrons and is denoted 14 C. Over time, 14 C decays into 12 C. Sometimes the isotope of an element is denoted by writing the nucleon number after the chemical symbol, and not as a superscript.

Xenon tetroxide All eight valence electrons of xenon are involved in the bonds with the oxygen, and the oxidation state of the xenon atom is +8. Oxygen is the only element that can bring xenon up to its highest oxidation state; even fluorine can only give XeF6 (+6). Two other short-lived xenon compounds with an oxidation state of +8, XeO 3 F 2 and XeO 2 F 4, are accessible by the reaction of xenon tetroxide with xenon hexafluoride.

It's Elemental Due to its high atomic weight, xenon ions were used as a fuel in an experimental ion engine aboard the space probe Deep Space 1. Once thought to be completely inert, xenon will form compounds, usually with fluorine, oxygen and platinum. XePtF 6, XeF 2, XeF 4, XeF 6 and XeO 4 are some of the xenon compounds that have been formed.

Questions and Answers These different versions of hydrogen are called isotopes. All isotopes of a particular element have the same number of protons, but have a different number of neutrons. If you change the number of neutrons an atom has, you make an isotope of that element. Currently, scientists know of 118 different elements.

A high efficiency device for the detection of radioactive xenon isotopes A detector has been designed for the detection of sub-Becquerel amounts of the radioactive xenon isotopes 131m Xe and 133 Xe. High efficiency has been obtained by the condensation of the sample directly onto the surfaces of two closely spaced silicon surface-barrier detectors.

- Lead has four observationally stable isotopes, lead-204, lead-206, lead-207, and lead-208. The relative multitude of its stable isotopes relies on the fact that lead's atomic number of 82 is even, and is in fact a magic number.

- Xenon-129, a stable isotope that makes up about a quarter of naturally occurring xenon, turns out to be ideal for use in magnetic resonance imaging. Usually these instruments only detect hydrogen nuclei in water and fats-ideal for most tissue, but are of no use when looking at air spaces such as the lungs.

What makes some isotopes have an unstable nuclei and others not? For most of the element there are different isotopes, atoms with the same number of protons but different numbers of neutrons. For example, carbon atoms always have six protons, but may have six, seven, or eight neutrons. Some isotopes are stable, but others are radioactive. An isotope will be radioactive if its nuclei are unstable. Large atomic nuclei, with more than 93 protons and their associated complement of neutrons, are inherently unstable. Uranium and plutonium are examples of such elements.
