Carbon, a chemicalelement with the price C and also atomic number 6, is a non-metallic element withdifferent appearance means graphite has a black, metallic appearance when diamondhas a clear appearance. Carbon has actually three naturally occurring isotopes: 12C &13C (stable), and also 14C (radioactive).

You are watching: How many valence electron does carbon have

Carbon is thefourth many abundant element in the world after hydrogen, helium, andoxygen. Largely it is uncovered in the form of necessary compounds, and with combinewith air in the kind of carbon dioxide (CO2). The carbon atoms have the right to bond togetherin diverse forms which an outcome in the development of different allotropes. Graphite, diamond,and buckminsterfullerene room the best-known allotropes of carbon.

You are here toknow valence electron of carbon atom, aren’t you? Don’t worry along with carbonvalence electrons us will describe its valency also. But prior to that let’s havesome an easy ideas about what these 2 terms are:

Difference BetweenValence Electrons and Valency

Valence electronsare the total variety of electrons present in the outermost covering of an atom(i.e. In outermost orbital). The valence electrons because that a neutral atom is alwaysdefinite, it cannot be differed (more or less) in any kind of condition for a particularatom and also may or might not be same to the valency.


*

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

Carbon (C) ValenceElectrons

There are foursimple measures to discover out the valence electrons for carbon atom i m sorry are:

Step 1: discover theAtomic Number


*

To find out theatomic number of carbon, we deserve to use the routine table. With the help of theperiodic table, us can easily see the the atomic number of carbon is 6. Together itsatomic number is 6, it has six protons, and for neutral carbon, the number ofprotons are constantly equal to the number of electrons i.e. Has six electron inits nucleus.

Step 2: WriteElectron Configuration


*

Electronconfiguration is the setup of electron on the orbitals. The carbon atomhas a full of five electrons so, we have to put 6 electron in orbitals. The electronswill be placed in different orbitals according to the power level: <1s, 2s,2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f>. Now,

Carbon electronconfiguration C (6) =1s22s22p2(completeconfiguration).

= 2s22p2(condensed configuration).

Step3: DetermineValence Shell

As us know, thevalence covering of an atom have the right to be discovered from the highest variety of principlequantum numbers which room expressed in the ax of n, and also in 2s22p2, thehighest value of n is 2 so the the valence covering of B is2s22p2.

Step 4: FindValence Electrons

The full number ofelectrons current in the valence covering of an atom are called valence electrons,and there are a complete of 4 electrons existing in the valence shell of carbon(2s22p2). Thus,carbon has four valence electrons.

Valency of Carbon (C)

There room manydifferent means to uncover out the valency of an atom which shows the ability ofan atom to bond with various other atoms. Valence describes how quickly an atom or afree radical can integrate with various other chemical species. The valency of one atom isdetermined based on the number of electrons lost, gained, or common withanother atom at the time of shortcut formation.

An atom is claimed tobe stable once its outermost shells have actually eight electrons (except H & He).If the total number of electrons in outermost shells is between one come four,the atom has actually positive valency and if electron are in between four come eight, thevalency is calculate by subtracting from eight and valency will certainly be zero. Atomshaving 4 outermost electrons own both optimistic and negative valency, andatoms having actually eight outermost electrons, valency will certainly be zero (i.e. Noblegases).

Elements like carboncan with the stable state (nearest inert gas configuration) one of two people by losing 4outermost electrons or by gaining 4 electrons.So the the valency the carbonis 4 (tetravalency).

Note: Carbon hasboth +4 & -4 valency/oxidation states. If the loses three electrons to with a stablestate (i.e. He), that is valency will be +4. Yet if the gains five electrons toreach a stable state (i.e. Ne), the valency will certainly be -4 as described above. For instance in CO2, the oxidation state that carbon is +4 when in CH4, the oxidation state is -4.

In an additional sense, acarbon atom can form four covalent bond in chemistry bonding (For example CH4,CCl4, etc.), and also that what valency is, the maximum capacity to form bonds withdifferent atoms at the moment of chemistry reactions.

We can likewise find the valency the carbon v thehelp the the periodic table. As carbon belongs to group 14 (IVa) follow me withsilicon (Si), germanium (Ge), tin (Sn), command (Pb), and also flerovium (Fl). All theseelements have actually a valency state of 4 (tetravalent).

Clarification: Valency is the combining capacity of an element at the time of chemical bonding. So the valency can not be an unfavorable or positive, it is just a number value between 0 to 4.
