Xenon has five electron shells.
8
Yes. Helium, Xenon, and Neon have stable electron numbers (octette rule).
The number of period corresponds to the total number of electron rings.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.

There are no valence electrons.
Xenon has five electron shells.
There are 8 of them.
Three electron shells would be completely filled by a neutral xenon atom.
Eight: the valency shell is full.
Xenon's atomic number is 54. Therefore, neutral xenon has 54 protons and 54 electrons. Its configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6. Thus, xenon has 5 electron shells.
All eight: the shell is full.
None.
