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

You are watching: How many valence electrons in c

Carbon is thefourth most abundant facet in the universe after hydrogen, helium, andoxygen. Mostly it is found in the form of necessary compounds, and also with combinewith wait in the kind 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 are the best-known allotrope of carbon.

You are below toknow valence electrons of carbon atom, aren’t you? Don’t worry in addition to carbonvalence electrons us will explain its valency also. But before that let’s havesome an easy ideas about what these two terms are:

Difference BetweenValence Electrons and also Valency

Valence electronsare the total number of electrons present in the outermost covering of one atom(i.e. In outermost orbital). The valence electrons for a neutral atom is alwaysdefinite, it cannot be varied (more or less) in any type of condition because that a particularatom and may or might not be equal to its valency.


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

Carbon (C) ValenceElectrons

There are foursimple actions to uncover out the valence electrons for carbon atom i m sorry are:

Step 1: find theAtomic Number


To uncover out theatomic variety of carbon, we can use the routine table. Through the assist 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 to the number of electrons i.e. Has six electrons inits nucleus.

Step 2: WriteElectron Configuration


Electronconfiguration is the setup of electrons on the orbitals. The carbon atomhas a total of five electrons so, we need to put 6 electrons in orbitals. The electronswill 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,

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

= 2s22p2(condensed configuration).

Step3: DetermineValence Shell

As us know, thevalence covering of an atom deserve to be discovered from the highest variety of principlequantum number which are expressed in the ax of n, and also in 2s22p2, thehighest worth of n is 2 so that the valence covering of B is2s22p2.

Step 4: FindValence Electrons

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

Valency the Carbon (C)

There room manydifferent means to uncover out the valency of one atom which reflects the ability ofan atom to bond with other atoms. Valence explains how easily an atom or afree radical can incorporate with other chemical species. The valency of one atom isdetermined based on the variety of electrons lost, gained, or common withanother atom at the time of bond formation.

An atom is stated tobe stable when its outermost shells have eight electron (except H & He).If the total variety of electrons in outermost shells is in between one to four,the atom has actually positive valency and if electrons are between four come eight, thevalency is calculation by subtracting from eight and valency will certainly be zero. Atomshaving 4 outermost electrons possess both optimistic and an adverse valency, andatoms having actually eight outermost electrons, valency will certainly be zero (i.e. Noblegases).

Elements choose carboncan with the secure state (nearest inert gas configuration) one of two people by shedding 4outermost electrons or by gaining 4 electrons.So that the valency of carbonis 4 (tetravalency).

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

In one more sense, acarbon atom can type four covalent binding in chemical bonding (For example CH4,CCl4, etc.), and also that what valency is, the maximum capacity to kind bonds withdifferent atoms at the time of chemistry reactions.

We can likewise find the valency that carbon through thehelp of the routine table. Together carbon belongs to team 14 (IVa) along withsilicon (Si), germanium (Ge), believe (Sn), lead (Pb), and also flerovium (Fl). All theseelements have actually a valency state of 4 (tetravalent).

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