Carbon, a chemicalelement with the price C and atomic number 6, is a non-metallic aspect withdifferent appearance way graphite has a black, metallic appearance if diamondhas a clear appearance. Carbon has actually three naturally occurring isotopes: 12C &13C (stable), and also 14C (radioactive).
You are watching: Number of valence electrons in carbon
Carbon is thefourth most abundant element in the world after hydrogen, helium, andoxygen. Mostly it is found in the form of organic compounds, and with combinewith waiting in the kind of carbon dioxide (CO2). The carbon atoms deserve to bond togetherin varied forms which result in the development of different allotropes. Graphite, diamond,and buckminsterfullerene space the best-known allotropes of carbon.
You are below toknow valence electron of carbon atom, aren’t you? Don’t worry together with carbonvalence electrons us will define its valency also. But before that let’s havesome straightforward ideas around what these two terms are:
Difference BetweenValence Electrons and Valency
Valence electronsare the total number of electrons existing in the outermost covering of one atom(i.e. In outermost orbital). The valence electrons for a neutral atom is alwaysdefinite, it can not be differed (more or less) in any condition for a particularatom and also may or may not be same to the valency.
Valency is definedas the total variety of electrons one atom can lose, gain, or share in ~ the timeof bond formation to get a stable digital configuration i.e. To complete anoctet. The valency of one atom have the right to be variable in various compounds or chemicalreactions as result of the various bonding circumstances. Most of the time valencyvaries/changes due to adjust in oxidation and reduction states.
Carbon (C) ValenceElectrons
There room foursimple procedures to uncover out the valence electrons because that carbon atom i beg your pardon are:
Step 1: discover theAtomic Number
To find out theatomic number of carbon, we deserve to use the routine table. With the assist of theperiodic table, we can conveniently see the the atomic number of carbon is 6. Together itsatomic number is 6, it has actually six protons, and for neutral carbon, the number ofprotons are constantly equal come 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 full of five 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).
Step3: DetermineValence Shell
As we 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 in
Step 4: FindValence Electrons
The total number ofelectrons existing in the valence covering of one atom are called valence electrons,and there space a total of 4 electrons existing in the valence covering of carbon(2s22p2). Thus,carbon has four valence electrons.
Valency the Carbon (C)
There room manydifferent methods to discover out the valency of one atom which reflects the ability ofan atom to bond with various other atoms. Valence describes how conveniently an atom or afree radical can integrate with various other chemical species. The valency of an atom isdetermined based on the number of electrons lost, gained, or common withanother atom at the moment of bond 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 electrons are between four come eight, thevalency is calculate by subtracting from eight and also valency will be zero. Atomshaving four outermost electrons possess both optimistic and an adverse valency, andatoms having eight outermost electrons, valency will certainly be zero (i.e. Noblegases).
Elements prefer carboncan with the secure state (nearest inert gas configuration) either by losing 4outermost electron or by acquiring 4 electrons.So the 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), its valency will be +4. Yet if that gains five electrons toreach a secure state (i.e. Ne), that is valency will certainly be -4 as explained 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 bond in chemistry bonding (For example CH4,CCl4, etc.), and also that what valency is, the maximum capacity to kind bonds withdifferent atoms at the moment of chemical reactions.We can additionally find the valency the carbon v thehelp that the routine table. Together carbon belong to team 14 (IVa) along withsilicon (Si), germanium (Ge), tin (Sn), lead (Pb), and also flerovium (Fl). All theseelements have actually a valency state of four (tetravalent).

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