Carbon, a chemicalelement through the prize C and also atomic number 6, is a non-metallic aspect withdifferent appearance way graphite has actually a black, metallic appearance when diamondhas a clear appearance. Carbon has actually three naturally arising isotopes: 12C &13C (stable), and also 14C (radioactive).
You are watching: How many valence shell electrons does the element carbon have?
Carbon is thefourth many abundant facet in the cosmos after hydrogen, helium, andoxygen. Mainly it is discovered in the type of organic compounds, and also with combinewith waiting in the type of carbon dioxide (CO2). The carbon atoms have the right to bond togetherin diverse forms which result in the development of various allotropes. Graphite, diamond,and buckminsterfullerene room the best-known allotrope of carbon.
You are here toknow valence electron of carbon atom, aren’t you? Don’t worry along with carbonvalence electrons we will define its valency also. But before that let’s havesome basic ideas around what these 2 terms are:
Difference BetweenValence Electrons and also Valency
Valence electronsare the total number of electrons existing 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 may not be same to the valency.
Valency is definedas the total number of electrons an atom have the right to lose, gain, or share in ~ the timeof bond formation to get a stable electronic configuration i.e. To complete anoctet. The valency of an atom have the right to be change in different compounds or chemicalreactions because of the different bonding circumstances. Most of the moment valencyvaries/changes due to readjust in oxidation and reduction states.
Carbon (C) ValenceElectrons
There are foursimple procedures to uncover out the valence electrons because that carbon atom i m sorry are:
Step 1: discover theAtomic Number
To uncover out theatomic variety of carbon, we have the right to use the regular table. V the aid of theperiodic table, us can quickly see that the atomic variety of carbon is 6. As 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 actually six electrons inits nucleus.
Step 2: WriteElectron Configuration
Electronconfiguration is the setup of electrons on the orbitals. The carbon atomhas a total of 5 electrons so, we have to put 6 electron in orbitals. The electronswill be placed in different 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).
Step3: DetermineValence Shell
As we know, thevalence shell of one atom can be discovered from the highest number of principlequantum number which space expressed in the term of n, and in
Step 4: FindValence Electrons
The complete number ofelectrons present in the valence covering of an atom are called valence electrons,and there space a full of four electrons present in the valence covering of carbon(2s22p2). Thus,carbon has 4 valence electrons.
Valency of Carbon (C)
There space manydifferent methods to uncover out the valency of one atom which shows the capacity ofan atom to bond with various other atoms. Valence defines how easily an atom or afree radical can combine with other chemical species. The valency of one atom isdetermined based on the number of electrons lost, gained, or shared withanother atom at the time of shortcut formation.
An atom is claimed tobe stable when its outermost shells have eight electrons (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 electrons are between four to eight, thevalency is calculated by individually from eight and valency will certainly be zero. Atomshaving four outermost electrons own both confident 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 shedding 4outermost electrons or by gaining 4 electrons.So that 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), its valency will be +4. Yet if it gains five electrons toreach a steady state (i.e. Ne), that 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 an additional sense, acarbon atom can form four covalent binding in chemical bonding (For example CH4,CCl4, etc.), and that what valency is, the maximum capability to kind bonds withdifferent atoms at the moment of chemistry reactions.We can also find the valency the carbon through thehelp of the regular table. Together carbon belongs to team 14 (IVa) along withsilicon (Si), germanium (Ge), believe (Sn), command (Pb), and flerovium (Fl). Every theseelements have actually a valency state of 4 (tetravalent).

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