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

In chemicallaboratory, dinitrogen have the right to be all set by dealing with an aqueous solution 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 we will define its valency also. But prior to that let’s havesome straightforward ideas around what these 2 terms are:

Difference BetweenValence Electrons and Valency

Valence electronsare the total number of electrons current in the outermost shell of an atom(i.e. In outermost orbital). The valence electrons for a neutral atom arealways definite, it cannot be varied (more or less) in any type of condition for aparticular atom and also may or might not be same to that is valency.


Valency is definedas the total number of electrons one atom deserve to lose, gain, or share at the timeof bond development to obtain a stable electronic configuration i.e. To complete anoctet. The valency of one atom deserve to be variable in different compounds or chemicalreactions as result of the different bonding circumstances. Many of the moment valencyvaries/changes early out to adjust in oxidation and also reduction states.

Nitrogen (N)Valence Electrons

There room foursimple measures to uncover out the valence electrons because that nitrogen atom i m sorry are:

Step 1: discover theAtomic Number


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

Step 2: WriteElectron Configuration


Electronconfiguration is the plan of electron on the orbitals. The nitrogenatom has a complete of 7 electron so, we have to put 7 electrons in orbitals. Theelectrons will certainly be put in different orbitals follow to the energy 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 we know, thevalence covering 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 of n is 2 so the the valence shell of nitrogen is2s22p3.

Step 4: FindValence Electrons

The full number ofelectrons current in the valence shell of one atom are dubbed valence electrons,and there space a total of five electrons existing in the valence covering of nitrogen(2s22p3). Thus,nitrogen has five valence electrons.

Valency of Nitrogen(N)

There are manydifferent ways to discover out the valency of an atom which mirrors the ability ofan atom to bond with other atoms. Valence describes how quickly an atom or afree radical can combine with various other chemical species. The valency of an atom isdetermined based upon the variety of electrons lost, gained, or common withanother atom at the moment of bond formation.

An atom is stated 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 come four,the atom has positive valency and also if electrons are between four come eight, thevalency is calculation by subtracting from eight and valency will be zero. Atomshaving four outermost electrons possess both confident and negative valency, andatoms having actually eight outermost electrons, valency will be zero (i.e. Noblegases).

Elements favor nitrogencan reach the stable state (nearest inert gas construction ) by getting 3electrons.So that the valency the nitrogen is 3 (trivalent).

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

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

We can additionally 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 the steel bismuth (Bi). This group elements are additionally called pnictogens. Every these elements have a valency of 3.

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

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