Xe has 77 neutrons.
Xenon is an element on the periodic table with the symbol Xe and atomic number 54. Xenon has several isotopes, including xenon-129 and xenon-131, which have different numbers of neutrons in their nuclei. Xenon is a colorless, odorless noble gas that is commonly used in various applications such as lighting and medical imaging.
There are 9 isotopes, so there is no the isotope.
Tin is the element with the most stable isotopes, ten. Xenon is second with nine isotopes. Both Xenon and Cesium have 36 possible isotopes, but 27 of Xenon's and 35 of Cesium's isotopes are radioactive. This means that they decay over time and "shed" particles. Hydrogen has the smallest amount of isotopes, with three total and two stable isotopes.
Xenon has five electron shells.

None of the isotopes of xenon ordinarily found in nature is radioactive. Like all elements, xenon has synthetic radioactive isotopes.
Xenon has eight stable naturally occuring isotopes. Besides these stable forms, there are over 40 unstable isotopes that have been studied.
The numer of neutrons depends on the isotope, which, as you've noted, Xenon has several of. Pick one.
Some isotopes of xenon do undergo radioactive decay to caesium.
Caesium and Xenon, with 36 isotopes each
It has mostly stable isotopes.
Xenon is an element on the periodic table with the symbol Xe and atomic number 54. Xenon has several isotopes, including xenon-129 and xenon-131, which have different numbers of neutrons in their nuclei. Xenon is a colorless, odorless noble gas that is commonly used in various applications such as lighting and medical imaging.
Most of the isotopes of xenon are stable and even those that do decay, have half-lives of more than a quadrillion years!
Each isotope of an element has a different number of neutrons. Number of neutrons = Atomic mass of the isotope - Atomic number of the element The atomic number of xenon is 54. For the list of xenon isotopes see the link below.
There are 9 isotopes, so there is no the isotope.
The number of unstable isotopes cannot be determined. Xenon has 9 stable or primordial isotopes. These include isotopes whose half-life is greater than 80 million years which is long enough for some of the atoms to have survived. It is also possible that so-called stable isotopes are not really stable but have half-lives of more than 10^22 years.Of the 9 Xenon isotopes,134Xe has a half-life of 1.1*10^16 years;136Xe has a half-life of 8.5*10^21 years;124Xe has a half-life of 1*10^17 years.
For stable isotopes, it will range from 123.9 grams to 135.9 g.
