Carbon, a chemicalelement v the prize C and also atomic number 6, is a non-metallic facet withdifferent appearance way graphite has actually a black, metallic appearance while diamondhas a clean appearance. Carbon has actually three naturally occurring isotopes: 12C &13C (stable), and also 14C (radioactive).

You are watching: Number of valence electrons for carbon

Carbon is thefourth most abundant aspect in the cosmos after hydrogen, helium, andoxygen. Greatly it is found in the kind of essential compounds, and also with combinewith wait in the form 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 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 explain its valency also. But before that let’s havesome straightforward ideas about what these 2 terms are:

Difference BetweenValence Electrons and Valency

Valence electronsare the total number of electrons current 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 because that a particularatom and may or may not be same to that is valency.


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

Carbon (C) ValenceElectrons

There are foursimple procedures to discover out the valence electrons because that carbon atom which are:

Step 1: discover theAtomic Number


To find out theatomic number of carbon, we deserve to use the periodic table. V the aid of theperiodic table, us can conveniently see that the atomic variety of carbon is 6. Together itsatomic number is 6, it has six protons, and also for neutral carbon, the number ofprotons are constantly equal to the number of electrons i.e. Has actually six electrons inits nucleus.

Step 2: WriteElectron Configuration


Electronconfiguration is the arrangement of electron on the orbitals. The carbon atomhas a total of five electrons so, we have to put 6 electrons in orbitals. The electronswill be put in various 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 we know, thevalence covering of an atom can be uncovered from the highest number of principlequantum number which room expressed in the ax of n, and in 2s22p2, thehighest value of n is 2 so the the valence shell of B is2s22p2.

Step 4: FindValence Electrons

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

Valency of Carbon (C)

There are manydifferent means to find out the valency of one atom which reflects the ability 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 an atom isdetermined based upon the variety of electrons lost, gained, or mutual withanother atom at the time of shortcut formation.

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

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

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

In another sense, acarbon atom can kind four covalent bonds in chemical bonding (For instance CH4,CCl4, etc.), and that what valency is, the maximum capability to form bonds withdifferent atom at the time of chemistry reactions.

We can likewise find the valency the carbon with thehelp that the periodic table. Together carbon belonging to group 14 (IVa) along withsilicon (Si), germanium (Ge), believe (Sn), command (Pb), and also flerovium (Fl). All theseelements have a valency state of 4 (tetravalent).

Clarification: Valency is the combining capacity of an facet at the time of chemistry bonding. So the valency cannot be an adverse or positive, the is just a number value between 0 come 4.
