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

You are watching: What is the valence electron of carbon

Carbon is thefourth most abundant aspect in the cosmos after hydrogen, helium, andoxygen. Mainly it is discovered in the kind of necessary compounds, and with combinewith waiting in the type of carbon dioxide (CO2). The carbon atoms deserve to bond togetherin diverse forms which an outcome in the formation of various allotropes. Graphite, diamond,and buckminsterfullerene space the best-known allotrope of carbon.

You are below toknow valence electron of carbon atom, aren’t you? Don’t worry in addition to carbonvalence electrons us will describe 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 present in the outermost shell of one atom(i.e. In outermost orbital). The valence electrons because that a neutral atom is alwaysdefinite, it cannot be varied (more or less) in any type of condition for a particularatom and also may or may not be equal to that valency.


*

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

Carbon (C) ValenceElectrons

There space foursimple steps to discover out the valence electrons because that carbon atom i beg your pardon are:

Step 1: discover theAtomic Number


*

To uncover out theatomic variety of carbon, we can use the periodic table. V the help of theperiodic table, us can quickly see that the atomic number of carbon is 6. As itsatomic number is 6, it has actually six protons, and also for neutral carbon, the number ofprotons are constantly equal come the number of electrons i.e. Has six electron inits nucleus.

Step 2: WriteElectron Configuration


*

Electronconfiguration is the arrangement of electrons on the orbitals. The carbon atomhas a complete of 5 electrons so, we need to put 6 electron in orbitals. The electronswill be placed in different orbitals according to the energy 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 we know, thevalence shell of one atom have the right to be found from the highest number of principlequantum numbers which room expressed in the ax of n, and also in 2s22p2, thehighest worth of n is 2 so the the valence shell of B is2s22p2.

Step 4: FindValence Electrons

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

Valency that Carbon (C)

There room manydifferent means to uncover out the valency of one atom which reflects the capability ofan atom come bond with other atoms. Valence describes how conveniently an atom or afree radical can incorporate with various other chemical species. The valency of one atom isdetermined based on the variety of electrons lost, gained, or mutual withanother atom at the time of link formation.

An atom is claimed tobe stable when its outermost shells have actually eight electron (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 in between four to eight, thevalency is calculated by individually from eight and valency will be zero. Atomshaving 4 outermost electrons own both optimistic and an unfavorable valency, andatoms having actually eight outermost electrons, valency will be zero (i.e. Noblegases).

Elements prefer carboncan reach the stable state (nearest inert gas configuration) either by losing 4outermost electron or by acquiring 4 electrons.So that the valency that carbonis 4 (tetravalency).

Note: Carbon hasboth +4 & -4 valency/oxidation states. If that loses 3 electrons to reach a stablestate (i.e. He), that is valency will be +4. But if the gains 5 electrons toreach a stable state (i.e. Ne), its valency will certainly be -4 as explained above. For example in CO2, the oxidation state of carbon is +4 if in CH4, the oxidation state is -4.

In an additional sense, acarbon atom can kind four covalent binding in chemistry bonding (For instance CH4,CCl4, etc.), and also that what valency is, the maximum ability to type bonds withdifferent atom at the moment of chemistry reactions.

We can also find the valency of carbon through thehelp that the regular table. Together carbon belongs to team 14 (IVa) along withsilicon (Si), germanium (Ge), tin (Sn), command (Pb), and flerovium (Fl). Every theseelements have a valency state of 4 (tetravalent).

Clarification: Valency is the combining volume of an aspect at the moment of chemistry bonding. So that valency cannot be negative or positive, it is simply a number value between 0 come 4.
