Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^1 Short-hand version: [Xe] 6s^1 Note: The "^" symbol means the the following number is in the form of a superscript.
The electron configuration of Cs, or cesium starts with the base state of [Xe]. The outer shell is 6s1 which shows one valence electron.
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6d10 5s2p6 6s1
The electron configuration of caesium is [Xe]6s1.
The abbreviated electron configuration of Cs is [Xe]6s1.
[Xe],6s1
Se and Te
Cs (cesium) is in group I of the periodic table, and has 1 valence electron. This is very easy to lose, and so Cs loses this one electron to become the cesium cation, Cs^1+
When cesium forms an ion, it loses 1 electron to form the Cs+ cation. This is very easy for cesium to do because of its very low electronegativity, which is a measure of the attraction between the nucleus and the electrons.
Both sodium (Na) and cesium (Cs) are alkali metals in Group 1 of the periodic table. They both have one valence electron in the outermost shell. However, between the two, cesium has 3 more energy levels than sodium (sodium is in row 3, cesium is in row 6).
Cesium loses just one electron to form Cs+
Cs does not have a nobel gas electron configuration, as it contains one valence electron in its outermost s orbital. Be3+ also does have a nobel gas electron configuration, as this occurs when Be has a 2+ charge (the typical Be ion is Be2+).
The electron configuration of caesium is: [Xe]6s1.
Cs typically has a +1 charge, meaning it loses one electron to achieve a full outer shell configuration.
Be3+ has only 2 valence electron and not 8.

Cesium loses just one electron to form Cs+
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.
The condensed version (which you want to use for cesium!) is [Xe]6s1 It means cesium has all the electrons in the same places that xenon has, plus one valence electron way out in the 6th level.
