Verified step by step guidance1
Identify the group number of xenon (Xe) in the periodic table. Xenon is a noble gas located in Group 18.
Recall that elements in Group 18 have a full outer shell of valence electrons, which corresponds to 8 valence electrons (except for helium, which has 2).
Understand that valence electrons are the electrons in the outermost shell of an atom that participate in chemical bonding.
Confirm that xenon's electron configuration ends with the 5p orbital fully filled, indicating a complete octet in its valence shell.
Conclude that xenon has 8 valence electrons based on its position in Group 18 and its electron configuration.
