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

You are watching: Number of valence electrons in xenon

It is supplied in speed lamps, arc lamps, and additionally used together generalanesthesia. Mostly noble gases perform not react with various other atoms but unlikelyxenon readily reacts through fluorine to form different fluorides. XeF6, XeF4and XeF2 space the three secure fluorides the xenon. XeF deserve to be produced however theoretically, that is extremely unstable. The can additionally reacts with chlorine, bromine, and iodine toform XeCl2, XeCl4, XeClF, XeBr and also XeI.

You are right here to know valence electrons and also valency of xenon,aren’t you? But before that let’s have actually some ideas about what these two termsare:

Difference between Valence Electrons and also Valency

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


Valency is defined as the total variety of electrons one atomcan lose, gain, or share at the moment of bond formation to gain a stableelectronic configuration i.e. To finish an octet. The valency of an atom canbe change in various compounds or chemical reactions because of the differentbonding circumstances. Most of the moment valency varies/changes early to readjust inoxidation and also reduction states.

Xenon (Xe) Valence Electrons

There are four straightforward steps to uncover out the valenceelectrons for xenon atom i m sorry are:

Step 1: find the atomic Number


To uncover out the atomic number of xenon, we deserve to use theperiodic table. With the help of the routine table, us can easily see the the atomic number of xenon is 54. As its atom number is 54, it has actually 54 protons,and because that neutral xenon, the variety of protons is constantly equal come the number ofelectrons i.e. Xe has 54 electrons in that is nucleus.

Step 2: write Electron Configuration


Electron construction is the setup of electron onthe orbitals. The xenon atom has actually a total of 54 electrons so, we need to put 54 electron in orbitals.The electrons will certainly be inserted in orbital according come this power 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 uncovered fromthe highest variety of principle quantum numbers which is expressed in the termof n, and in4d¹⁰5s²5p⁶, the highest value the n is 5 so that the valence covering of Xeis5s²5p⁶.

Step 4: find Valence Electrons

The total variety of electrons present in the valence shellof one atom is dubbed valence electrons, and also there is only one electron presentin the valence covering of xenon (5s²5p⁶). Thus, xenon has actually eight valence electrons.

Valency that Xenon (Xe)

There are countless different means to uncover out the valency of atom which shows the capability of an atom to bond with various other atoms. Valencedescribes how easily an atom or a free radical can integrate with various other chemicalspecies. The valency of one atom is determined based on the variety of electronslost, gained, or mutual with one more atom at the time of bond formation.

An atom is said 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 between four to eight, the valency is calculation by subtractingfrom eight and also valency will be zero. Atoms having four outermost electronspossess both confident and an adverse valency, and atoms having actually eight outermostelectrons, valency will certainly be zero (i.e. Noble gases).

Noble gases favor xenon have actually eight valence electron so itdoes not need to shed or acquire electrons to complete their energy shell i.e. Stableoctet. So that they perform not have actually any tendency to incorporate with various other elementswhich renders the valency that xenon zero. Because valency is all around lose, gain, orshare of electrons.

We can additionally find the valency the xenon v the help of a periodictable. Together xenon belongs to team 8A which are teams of noble gases having actually valencyzero.
