No. there are no unpaired electrons in xenon. In neutral form, xenon will have 8 valence electrons.
One
The same number of valence electrons as xenon.
There are 2 electrons in the first valence shell ("orbital"). The first orbital is an "s" orbital. If the atom is neutral in charge and there is only 1 electron - you have Hydrogen. If the atom is neutral in charge and you have only 2 electrons - you have Helium. Since the outermost shell of electrons is full, considerable chemical stability is conferred to the Helium atom, thus it is a member of the "Noble Gases" - those that have full comlpements of electrons in their outer shells, the others being Neon, Argon, Krypton, Xenon, and Radon.
One. A hydrogen atom contains only one electron, and it is a valence electron.
One. Sodium is found in Group 1, which is characterized by having one valence electron, so by extension, potassium, rubidium, cesium, and francium also have one valence electron.

A valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.) It is an electron in the outermost shell of the atom.
when it is on the very outside level away from the nucleusA valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.)It is an electron in the outermost shell of the atom.
All the elements in the first column of the Periodic Table (lithium, sodium, potassium, rubidium, cesium, and francium) have one valence electron. I also believe Helium has one valence electron.
Group one has one valence electron, and group two has two valence electrons
A cesium atom has 1 valence electron. It is an alkali metal, and all alkali metals have 1 valence electron. The electron configuration for cesium is (Rn)7s1. The single electron in the 7s sublevel is its valence electron.
Hydrogen has only one electron. Just the one. And it is a valence electron.
Alkali metals have one valence electron.
