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

You are watching: How many valence electrons do carbon have

Carbon is thefourth many abundant aspect in the universe after hydrogen, helium, andoxygen. Largely it is found in the kind of necessary compounds, and also with combinewith air in the type of carbon dioxide (CO2). The carbon atoms can bond togetherin varied forms which result in the development of various allotropes. Graphite, diamond,and buckminsterfullerene space the best-known allotropes of carbon.

You are below toknow valence electrons of carbon atom, aren’t you? Don’t worry along with carbonvalence electrons we will describe its valency also. But before that let’s havesome basic ideas about what these 2 terms are:

Difference BetweenValence Electrons and also Valency

Valence electronsare the total variety of electrons present in the outermost shell of an 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 because that a particularatom and may or might not be equal to that is valency.


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

Carbon (C) ValenceElectrons

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

Step 1: find theAtomic Number


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

Step 2: WriteElectron Configuration


Electronconfiguration is the setup of electrons on the orbitals. The carbon atomhas a complete of five electrons so, we need to put 6 electrons in orbitals. The electronswill be inserted 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 we know, thevalence shell of one atom have the right to be uncovered from the highest variety of principlequantum numbers which space 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 total number ofelectrons present in the valence covering of an atom are dubbed valence electrons,and there space a total of four electrons current in the valence covering of carbon(2s22p2). Thus,carbon has 4 valence electrons.

Valency that Carbon (C)

There are manydifferent methods to discover out the valency of one atom which reflects the capability ofan atom to bond with other atoms. Valence describes how quickly an atom or afree radical can integrate with 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 bond formation.

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

Elements like carboncan with the secure state (nearest inert gas configuration) either by losing 4outermost electrons or by acquiring 4 electrons.So the the valency that carbonis 4 (tetravalency).

Note: Carbon hasboth +4 & -4 valency/oxidation states. If it loses three electrons to with a stablestate (i.e. He), the valency will certainly be +4. Yet if that gains five electrons toreach a stable state (i.e. Ne), that is valency will 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 type four covalent bonds in chemical bonding (For example CH4,CCl4, etc.), and also that what valency is, the maximum ability to form bonds withdifferent atoms at the time of chemical reactions.

We can likewise find the valency of carbon with thehelp of the regular table. Together carbon belong to group 14 (IVa) follow me withsilicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). Every theseelements have a valency state of four (tetravalent).

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