Xenon, a chemical facet with the prize Xe and atomic number 54,is a colorless, odorless, tasteless, non-flammable, nontoxic inert gas. It is very rare noble gas uncovered on the earth"s surface.

You are watching: How many valence electrons does xe have

It is supplied in speed lamps, arc lamps, and additionally used together generalanesthesia. Mainly noble gases execute not reaction with various other atoms yet unlikelyxenon conveniently reacts with fluorine to kind different fluorides. XeF6, XeF4and XeF2 room the three steady fluorides the xenon. XeF can be produced but theoretically, the is extremely unstable. The can likewise reacts v chlorine, bromine, and also iodine toform XeCl2, XeCl4, XeClF, XeBr and also XeI.

You are right here to recognize valence electrons and also valency of xenon,aren’t you? But prior to that let’s have some ideas around what these 2 termsare:

Difference in between Valence Electrons and also Valency

Valence electrons space the total number of electrons presentin the outermost covering of an atom (i.e. In outermost orbital). The valenceelectrons for a neutral atom is always definite, it can not be differed (more orless) in any kind of condition because that a details atom and may or might not be same to itsvalency.


Valency is characterized as the total variety of electrons one atomcan lose, gain, or share at the time of bond development to gain a stableelectronic configuration i.e. To complete an octet. The valency of one atom canbe change in different compounds or chemistry reactions due to the differentbonding circumstances. Most of the moment valency varies/changes early to adjust inoxidation and also reduction states.

Xenon (Xe) Valence Electrons

There are four straightforward steps to find out the valenceelectrons for xenon atom i beg your pardon are:

Step 1: discover the atomic Number


To find out the atomic variety of xenon, we have the right to use theperiodic table. With the assist of the routine table, we can easily see that the atomic variety of xenon is 54. As its atom number is 54, it has actually 54 protons,and for neutral xenon, the number of protons is always equal come the number ofelectrons i.e. Xe has 54 electron in the nucleus.

Step 2: compose Electron Configuration


Electron construction is the plan of electrons onthe orbitals. The xenon atom has a complete of 54 electrons so, we need to put 54 electrons in orbitals.The electrons will be inserted in orbital according come this energy levels: <1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f>. Now,

Xenon electron construction Xe (54) =1s22s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s²5p⁶(completeconfiguration)

= 4d¹⁰5s²5p⁶ (condensed configuration).

Step3: identify Valence Shell

As we know, the valence shell of one atom have the right to be uncovered fromthe highest number of principle quantum numbers which is expressed in the termof n, and in4d¹⁰5s²5p⁶, the highest value of n is 5 so that the valence shell of Xeis5s²5p⁶.

Step 4: discover Valence Electrons

The total number of electrons present in the valence shellof one atom is called valence electrons, and also there is just one electron presentin the valence shell of xenon (5s²5p⁶). Thus, xenon has eight valence electrons.

Valency the Xenon (Xe)

There are numerous different ways to uncover out the valency of atom which shows the capability of one atom to bond with other atoms. Valencedescribes how quickly an atom or a cost-free radical can integrate with other chemicalspecies. The valency of an atom is determined based upon the variety of electronslost, gained, or shared with one more atom at the time of link formation.

An atom is claimed to be stable once its outermost shells haveeight electrons (except H & He). If the total number of electrons inoutermost shells is in between one come four, the atom has actually positive valency and ifelectrons are in between four come eight, the valency is calculation by subtractingfrom eight and also valency will be zero. Atoms having 4 outermost electronspossess both positive and an unfavorable valency, and also atoms having eight outermostelectrons, valency will be zero (i.e. Noble gases).

Noble gases favor xenon have eight valence electron so itdoes not call for to lose or acquire electrons to finish their energy shell i.e. Stableoctet. So the they execute not have any tendency to integrate with various other elementswhich renders the valency that xenon zero. Since valency is all about lose, gain, orshare the electrons.

We can also find the valency that xenon with the assist of a periodictable. As xenon belong to team 8A i m sorry are teams of noble gases having actually valencyzero.
