Antonio Rostagni appears to be a name associated with various contexts, but without more specific information, it's difficult to determine exactly who or what you are referring to.

Xenon (Xe) is a noble gas that has several isotopes, which are variations of the element with the same number of protons but different numbers of neutrons. The most common isotopes of xenon, along with their relative abundances and characteristics, include: 1. **Xenon-124 (Xe-124)**: This isotope has 54 protons and 70 neutrons. It is stable and constitutes about 0.1% of natural xenon.

Ytterbium (Yb) is a chemical element with the atomic number 70 and belongs to the lanthanide series. It has several isotopes, which are variants of the element with the same number of protons but different numbers of neutrons.

Medical isotopes are radioactive isotopes used in the diagnosis and treatment of various medical conditions, primarily in the field of nuclear medicine. These isotopes are utilized for their ability to emit radiation, which can be detected by imaging equipment for diagnostic purposes or used for targeted therapy.

A monoisotopic element is an element that has only one stable isotope, meaning that all the atoms of that element have the same atomic mass and nuclear composition. Such elements do not have multiple isotopes that are stable and can be found in nature. For example, the element fluorine (atomic number 9) has only one stable isotope, fluorine-19. Therefore, fluorine is considered a monoisotopic element.
