The Xe atom has an expanded valence shell with more than eight electrons around it. Key Takeaway There are three violations to the octet rule: odd-electron molecules, electron-deficient molecules, and expanded valence shell molecules.
Sig sauer p226 navy vs mk25
The highest energy level (valence shell) of a Group 13 element already has 2 electrons in an s subshell, so the next electron occupies a p subshell to make 3 valence electrons in total (2 s electrons + 1 p electron). As you proceed from left to right across the Period from Group 13 to Group 18 elements, electrons are being added to the p subshell.

Xe is much larger than Ne, so its valence electrons are more easily polarized by a highly electronegative atom, e.g F, such that 2 F atoms can form single covalent bonds with Xe's d-orbital electrons.

For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used. The electron configuration can be visualized as the core electrons, equivalent to the noble gas of the preceding period, and the valence electrons (e.g. [Xe] 6s2 for barium).

Xenon is an element with an atomic number of 54, which means that it has 54 protons and 54 electrons. Its average atomic mass is 131.293 amu, which means that its atomic mass number is 131, with 77 neutrons. Xenon's electron configuration is 2,8,18,18,8, and the last number represents the number of valence electrons the element has: 8.

Valence electronsare the outermost electrons of an atom and are normally the only electrons that participate in chemical bonding. (Note:For the main group elements only the outermost electrons are involved in chemical reactions. In transition metals, though, some inner-shell electrons also participate.)
