Xenon, a chemical aspect with the price Xe and atomic number 54,is a colorless, odorless, tasteless, non-flammable, nontoxic inert gas. It is really rare noble gas discovered on the earth"s surface.

You are watching: How many valence electrons does xe have

It is used in speed lamps, arc lamps, and also used together generalanesthesia. Mostly noble gases execute not react with various other atoms however unlikelyxenon readily reacts with fluorine to form different fluorides. XeF6, XeF4and XeF2 room the three stable fluorides the xenon. XeF have the right to be produced however theoretically, the is highly unstable. It can also reacts v chlorine, bromine, and iodine toform XeCl2, XeCl4, XeClF, XeBr and also XeI.

You are below to know valence electrons and valency of xenon,aren’t you? But prior to that let’s have actually some ideas around what these two termsare:

Difference in between Valence Electrons and also Valency

Valence electrons room the total variety of electrons presentin the outermost shell of one atom (i.e. In outermost orbital). The valenceelectrons because that a neutral atom is constantly definite, it can not be varied (more orless) in any kind of condition because that a specific atom and also may or may not be same to itsvalency.


Valency is identified as the total variety of electrons one atomcan lose, gain, or re-publishing at the time of bond development to obtain a stableelectronic configuration i.e. To finish an octet. The valency of one atom canbe variable in various compounds or chemistry reactions because of the differentbonding circumstances. Many of the time valency varies/changes due to readjust inoxidation and reduction states.

Xenon (Xe) Valence Electrons

There space four basic steps to discover out the valenceelectrons for xenon atom which are:

Step 1: discover the atom Number


To find out the atomic variety of xenon, we deserve to use theperiodic table. With the assist of the routine table, we can quickly see the the atomic number of xenon is 54. As its atomic number is 54, it has 54 protons,and because that neutral xenon, the number of protons is always equal to 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 have to put 54 electron in orbitals.The electrons will certainly be put in orbit 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 configuration Xe (54) =1s22s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s²5p⁶(completeconfiguration)

= 4d¹⁰5s²5p⁶ (condensed configuration).

Step3: determine Valence Shell

As us know, the valence shell of one atom have the right to be found fromthe highest variety of principle quantum numbers which is express in the termof n, and also in4d¹⁰5s²5p⁶, the greatest value the n is 5 so that the valence covering of Xeis5s²5p⁶.

Step 4: discover Valence Electrons

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

Valency of Xenon (Xe)

There are numerous different means to uncover out the valency of atom which reflects the capacity of an atom to bond with various other atoms. Valencedescribes how quickly an atom or a cost-free radical can incorporate with various other chemicalspecies. The valency of one atom is determined based upon the variety of electronslost, gained, or common with an additional atom at the time of link formation.

An atom is claimed to be stable as soon as its outermost shells haveeight electron (except H & He). If the total variety of electrons inoutermost shells is between one to four, the atom has positive valency and ifelectrons are in between four to eight, the valency is calculated by subtractingfrom eight and valency will be zero. Atoms having four outermost electronspossess both optimistic and an adverse valency, and atoms having eight outermostelectrons, valency will certainly be zero (i.e. Noble gases).

Noble gases prefer xenon have eight valence electron so itdoes not require to lose or obtain electrons to finish their energy shell i.e. Stableoctet. So that they execute not have any propensity to incorporate with other elementswhich makes the valency of xenon zero. Since valency is all about lose, gain, orshare of electrons.

We can additionally find the valency the xenon v the help of a periodictable. Together xenon belong to team 8A i m sorry are teams of noble gases having valencyzero.
