If I understand the question correctly, the answer is none.
A neutral atom of xenon has 6 energy levels, with 54 electrons occupying those levels. Xenon has 54 electrons in total, so no electrons would be left over in a neutral xenon atom.
A neutral xenon atom has 54 electrons. Two of its electron shells would be completely filled, with 2 and 8 electrons, leaving 44 electrons in the remaining electron shells.
Xenon has 54 electrons.
A neutral xenon atom would have 54 electrons filled in its electron shells.
An atom of xenon contains 54 electrons, the atomic number of xenon.

Xenon has 54 electrons 77 neutrons and 54 electrons
Xenon has eight unpaired electrons.
Xenon has 54 electrons.
The are none.
The element xenon (Xe) has 54 protons and 54 electrons.
There are no valence electrons.
