There are two ways to find the number of valence electrons in Xenon (Xe). The first is to use the Periodic Table to figure out how many electrons Xenon has in its valence shell. To do so, look at the Group number (groups are the columns). Xe is in Group 18 (also called 8A) and therefore Xenon has eight valence electrons (not that this method doesn’t work for the Transition Metals).

You can also look at the electron configuration to determine the number of valence electrons for Xe. The number of electrons in the highest energy level gives you the number of valence electrons. Using this method we’ll also determine that Xenon has eight valence electrons.

Elements with the same number of valence electrons as Xenon are Neon and Argon.
