Diagram of the nuclear composition, electron configuration, and valence orbitals of an atom of xenon-131 (atomic number: 54), an isotope of this eleme
Diagram of the nuclear composition, electron configuration, and valence orbitals of an atom of xenon-131 (atomic number: 54), an isotope of this element. The nucleus consists of 54 protons (blue) and 77 neutrons (red). The stability of an element's outer (valence) electrons determines its chemical and physical properties. Xenon is a noble gas in group 18, period 5, and the p-block of the periodic table. An inert gas found in trace amounts in the atmosphere, it is used in flash lamps and lasers.
