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

You are watching: Nitrogen has how many valence electrons

In chemicallaboratory, dinitrogen can be ready by dealing with an aqueous equipment ofammonium chloride and also sodium nitrite.

NH4Cl + NaNO2→ N2+ NaCl + 2 H2O

You are right here toknow valence electrons of the nitrogen atom, aren’t you? Don’t worry together with nitrogenvalence electrons we will define its valency also. But before that let’s havesome simple ideas around what these 2 terms are:

Difference BetweenValence Electrons and Valency

Valence electronsare the total number 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 may or might not be same to that valency.


Valency is definedas the total number of electrons an atom deserve to lose, gain, or share at the timeof bond development to obtain a stable digital configuration i.e. To complete anoctet. The valency of one atom can be variable in different compounds or chemicalreactions due to the various bonding circumstances. Most of the moment valencyvaries/changes due to adjust in oxidation and reduction states.

Nitrogen (N)Valence Electrons

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

Step 1: discover theAtomic Number


To uncover out theatomic number of nitrogen, we can use the periodic table. Through the help of theperiodic table, us can quickly see that the atomic variety of nitrogen is 7. Asits atom number is 7, it has actually 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 arrangement of electron on the orbitals. The nitrogenatom has actually a full of 7 electrons so, we need to put 7 electrons in orbitals. Theelectrons will certainly be put in various orbitals follow 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 we know, thevalence shell of one atom deserve to be discovered from the highest variety of principlequantum number which are expressed in the ax of n, and in 2s22p3, the highest value the n is 2 so the the valence covering of nitrogen is2s22p3.

Step 4: FindValence Electrons

The total number ofelectrons present in the valence covering of an atom are referred to as valence electrons,and there space a total of five electrons current in the valence shell of nitrogen(2s22p3). Thus,nitrogen has five valence electrons.

Valency the Nitrogen(N)

There are manydifferent methods to uncover out the valency of one atom which mirrors the capability ofan atom to bond with other atoms. Valence defines how conveniently an atom or afree radical can incorporate with various other chemical species. The valency of an atom isdetermined based on the number of electrons lost, gained, or mutual withanother atom at the time of shortcut formation.

An atom is said tobe stable when its outermost shells have eight electrons (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 calculate by individually from eight and also valency will certainly be zero. Atomshaving 4 outermost electrons own both confident and negative valency, andatoms having actually eight outermost electrons, valency will certainly be zero (i.e. Noblegases).

Elements like nitrogencan with the stable state (nearest inert gas configuration ) by gaining 3electrons.So the the valency the nitrogen is 3 (trivalent).

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

In one more sense, anitrogen atom can form a best of three covalent binding in chemistry bonding (Forexample: NH3, NCl3, etc.), and that what valency is, the maximum capability to formbonds with atoms at the time of chemical reactions.

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

Clarification:Valence electrons and valency are two various aspects. Valence electrons mean total electrons existing in the outermost shell of the aspect i.e. In the case of nitrogen , its valence electrons space 5.

But valency is the combining capacity of an element at the moment of chemistry bonding. So that valency can not be an adverse or positive, it is just a number value between 0 come 7. In the instance of nitrogen, valency is 3.
