Xe128

Xe128 is a stable isotope of the element Xenon. Xenon is a noble gas, meaning it is unreactive under normal conditions and has a full valence electron shell. The atomic number of Xenon is 54, indicating that each atom of Xenon has 54 protons. The number 128 in Xe128 refers to its mass number, which is the total number of protons and neutrons in the nucleus. Therefore, a Xe128 atom contains 54 protons and 74 neutrons (128 - 54 = 74).

As a stable isotope, Xe128 does not undergo radioactive decay. This distinguishes it from other isotopes of Xenon, some of which are radioactive and have applications in fields like medical imaging or dating. The natural abundance of Xe128 in terrestrial Xenon is approximately 1.91%. Due to its stability and inert nature, Xe128 is primarily of interest in scientific research, particularly in areas of nuclear physics and isotopic analysis. It can be used as a reference standard in mass spectrometry and in studies of nuclear reactions.
