Nitrogen, achemical facet with the symbol Si and also atomic number 14, is a colorless liquid,gas, or solid. At normal temperature and pressure, 2 atoms the nitrogen bind togetherto form colorless and also odorless dinitrogen (N2) gas. N2 forms around 78% that the earth’s setting which renders it the most abundant uncombined aspect on the earth"ssurface.

You are watching: How many valence electrons are in a neutral atom of nitrogen?

In chemicallaboratory, dinitrogen deserve to be prepared by dealing with an aqueous equipment ofammonium chloride and also sodium nitrite.

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

Difference BetweenValence Electrons and also Valency

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


Valency is definedas the total variety of electrons one atom can lose, gain, or share in ~ the timeof bond development to acquire a stable electronic configuration i.e. To complete anoctet. The valency of an atom deserve to be change in various compounds or chemicalreactions because of the different bonding circumstances. Many of the moment valencyvaries/changes early to change in oxidation and reduction states.

Nitrogen (N)Valence Electrons

There room foursimple measures to find out the valence electrons for nitrogen atom i m sorry are:

Step 1: discover theAtomic Number


To find out theatomic number of nitrogen, we can use the regular table. Through the aid of theperiodic table, us can easily see the the atomic variety of nitrogen is 7. Asits atom number is 7, it has actually 7 protons, and also for neutral nitrogen, the numberof proton is constantly equal come the number of electrons i.e. Has 7 electron inits nucleus.

Step 2: WriteElectron Configuration


Electronconfiguration is the setup of electrons on the orbitals. The nitrogenatom has a complete of 7 electrons so, we have to put 7 electrons in orbitals. Theelectrons will certainly be placed 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 have the right to be discovered from the highest variety of principlequantum number which room expressed in the term of n, and in 2s22p3, the greatest value the n is 2 so the the valence covering of nitrogen is2s22p3.

Step 4: FindValence Electrons

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

Valency the Nitrogen(N)

There are manydifferent ways to discover out the valency of one atom which shows the capacity ofan atom to bond with other atoms. Valence explains how quickly an atom or afree radical can integrate with other chemical species. The valency of an atom isdetermined based on the number of electrons lost, gained, or common withanother atom at the time of bond formation.

An atom is claimed tobe stable as soon as its outermost shells have actually eight electron (except H & He).If the total number of electrons in outermost shells is between one to four,the atom has positive valency and also if electrons are in between four to eight, thevalency is calculate by individually from eight and valency will certainly be zero. Atomshaving four outermost electrons own both positive and an unfavorable valency, andatoms having actually 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 that nitrogen is 3 (trivalent).

Note: Basically, the valency that nitrogen is 5 but it does not have d subshell so the the valencyreduces come 3 native 5. For example, phosphorous pentachloride (PCl5) deserve to exist asphosphorus has actually d-orbitals but nitrogen pentachloride (NCl5) can not exist. Althoughnitrogen has 5 valence electrons just a maximum of three have the right to take components inbond formation .

In one more sense, anitrogen atom can type a maximum of three covalent bonds in chemistry bonding (Forexample: NH3, NCl3, etc.), and also that what valency is, the maximum capacity to formbonds through atoms at the moment of chemistry reactions.

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

Clarification:Valence electrons and valency are two various aspects. Valence electrons mean complete electrons existing in the outermost shell of the aspect i.e. In the situation of nitrogen , that valence electrons room 5.

But valency is the combining capacity of an aspect at the moment of chemistry bonding. So that valency cannot be an unfavorable or positive, that is simply a number value between 0 come 7. In the situation of nitrogen, valency is 3.
