Nitrogen, achemical facet with the prize Si and atomic number 14, is a colorless liquid,gas, or solid. At normal temperature and pressure, two atoms of nitrogen bind togetherto type colorless and odorless dinitrogen (N2) gas. N2 forms about 78% that the earth’s atmosphere which renders it the most abundant uncombined facet on the earth"ssurface.

In chemicallaboratory, dinitrogen have the right to be all set by treating an aqueous equipment ofammonium chloride and also sodium nitrite.

You are here toknow valence electrons of the nitrogen atom, aren’t you? Don’t worry in addition to nitrogenvalence electrons us will describe its valency also. But before that let’s havesome straightforward ideas around what these two terms are:

Difference BetweenValence Electrons and also Valency

Valence electronsare the total variety of electrons present in the outermost covering of one atom(i.e. In outermost orbital). The valence electrons because that a neutral atom arealways definite, it can not be differed (more or less) in any kind of condition because that aparticular atom and may or may not be same to its valency.


Valency is definedas the total number of electrons an atom can lose, gain, or share at the timeof bond formation to obtain a stable electronic configuration i.e. To complete anoctet. The valency of one atom deserve to be change in different compounds or chemicalreactions because of the different bonding circumstances. Most of the time valencyvaries/changes early to adjust in oxidation and also reduction states.

Nitrogen (N)Valence Electrons

There are foursimple steps to find out the valence electrons because that nitrogen atom which are:

Step 1: discover theAtomic Number


To find out theatomic number of nitrogen, we can use the periodic table. V the help of theperiodic table, we can conveniently see that the atomic variety of nitrogen is 7. Asits atomic number is 7, it has actually 7 protons, and also for neutral nitrogen, the numberof protons is constantly equal to the number of electrons i.e. Has actually 7 electrons inits nucleus.

Step 2: WriteElectron Configuration


Electronconfiguration is the setup of electrons on the orbitals. The nitrogenatom has actually a complete of 7 electron so, we have to put 7 electron in orbitals. Theelectrons will certainly be inserted in various orbitals according to the power level:<1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f>. Now,

Nitrogen electronconfiguration N (7) =1s22s22p3(completeconfiguration).

= 2s22p3 (condensed configuration).

Step 3: DetermineValence Shell

As us know, thevalence shell of one atom can be found from the highest variety of principlequantum number which are expressed in the hatchet of n, and in 2s22p3, the highest possible value that n is 2 so the the valence covering of nitrogen is2s22p3.

Step 4: FindValence Electrons

The total number ofelectrons existing in the valence shell of one atom are called valence electrons,and there room a complete of 5 electrons current in the valence covering of nitrogen(2s22p3). Thus,nitrogen has 5 valence electrons.

Valency that Nitrogen(N)

There room manydifferent methods to find out the valency of one atom which reflects the capability ofan atom to bond with other atoms. Valence explains how conveniently an atom or afree radical can incorporate with other chemical species. The valency of one atom isdetermined based on the number of electrons lost, gained, or shared withanother atom at the time of bond formation.

An atom is said tobe stable as soon as its outermost shells have eight electrons (except H & He).If the total variety of electrons in outermost shells is between one to four,the atom has actually positive valency and if electron are between four come eight, thevalency is calculated by subtracting from eight and valency will be zero. Atomshaving four outermost electrons own both confident and an unfavorable valency, andatoms having eight outermost electrons, valency will be zero (i.e. Noblegases).

Elements prefer nitrogencan with the secure state (nearest inert gas construction ) by gaining 3electrons.So the the valency of nitrogen is 3 (trivalent).

Note: Basically, the valency the nitrogen is 5 however it walk not have actually d subshell so that the valencyreduces to 3 from 5. Because that example, phosphorous pentachloride (PCl5) have the right to exist asphosphorus has actually d-orbitals yet nitrogen pentachloride (NCl5) cannot exist. Althoughnitrogen has 5 valence electrons just a maximum of three can take parts inbond development .

In an additional sense, anitrogen atom can kind a maximum of 3 covalent binding in chemistry bonding (Forexample: NH3, NCl3, etc.), and also that what valency is, the maximum ability to formbonds through atoms at the time of chemical reactions.

We can also findthe valency the nitrogen with the aid of the regular table. Together nitrogenbelongs to team 15 (5A or VA) in addition to nonmetal phosphorus (P), themetalloids arsenic (As) and antimony (Sb), and also the steel bismuth (Bi). This group facets are likewise called pnictogens. Every these aspects have a valency the 3.

Clarification:Valence electrons and also valency space two different aspects. Valence electrons mean total electrons current in the outermost covering of the element i.e. In the instance of nitrogen , the valence electrons room 5.

But valency is the combining volume of an element at the time of chemical bonding. So that valency cannot be an unfavorable or positive, the is just a number value between 0 come 7. In the situation of nitrogen, valency is 3.
