Many that you have actually this inquiry of how plenty of electrons room in the last cell that carbon or how countless valence electron does carbon have?

In basic words, the variety of electrons current in the valence shell (last digital shell) is called valence electron.

You are watching: What is the number of valence electrons in carbon

The above two questions average the exact same thing, for this reason the carbon has four valence electrons. That is, there room 4 electrons present in the last cell the carbon.


Electronic construction of Carbon

If friend look at the electronic configuration of carbon, you have the right to see the there space two cells present in carbon. The first cell has two electrons and the critical cell has four electrons. Therefore look at this illustration of the electrical configuration that carbon.


Also, plenty of of you are confused in between the valency of carbon and also valence electron. So, for this, you require to know the difference between valency and also valence electrons.

What is Valancy that Carbon

According come the octet theory, in order because that each aspect to reach a steady state, the variety of electrons it leaves, or acquire or mutual shares in order to fill its octet, we will speak to that facet the valence. Thus, the valency of carbon is four.


After each element gains stability, its digital configuration will be prefer the nearest Nobel gas.

Many the you may be confused regarding where the word common share in meaning came from.

There are some aspects that deserve to neither get nor lose electrons in your last cell. In order because that this facet to be stable, the electrons in its critical cell need to be mutually mutual with other elements.


An example is a carbon. Since it never ever becomes a c-4 or c+4 ion by accepting or rejecting the 4 electrons in the critical cell in stimulate to get its stability. Due to the fact that in this case, you have to offer a lot of energy. For this, carbon always forms covalent bond by mutually share its own 4 electrons.


Question price on valency and valence electrons

The question-and-answer top top valence and also valence electrons is fully discussed below.

Problem1 In the situation of carbon, valency, and also valence electrons are equal. So will valence and valence electron be same or different in instance of all various other elements?

Valence electrons have actually no relation v Valency. Both are various concepts. Will certainly be same in the case of those aspects whose number of electrons in the critical cell will certainly be same to the variety of electrons obtained or rejected for the security of that element. Such as carbon, hydrogen, etc.

Problem2 What is the electron valency of neon and how plenty of electrons are present in its critical cell?

Neon is one inert element. That is, the neon will not obtain or reject any electrons. In this case, the valency that neon will certainly be zero. And also the critical cell that neon will always have 8 electrons. Thus, octet will stay met. The valency electron of neon will certainly be 8.

Problem3 What is the valency electron the oxide ion?

If girlfriend look in ~ the digital configuration that oxide ions, you have the right to see the there are 8 electrons existing in the valence cell. Thus, the valency electron the oxide ion is 8.

Problem4 Give instances of elements other 보다 carbon who valency and valence electrons will certainly be equal.

The valence that the hydrogen and the valence electron will certainly both be equal. Hydrogen’s valence electron will be 1.

Problem5 Give instances of aspects that have much more than one valence.

Such together iron. It has actually two valences, two and three. Iron will lose two electrons at some point and turn right into rt and at an additional time the will shed three electrons and turn into py. There are likewise many facets that have much more than one valence.

Problem6 How numerous valence electrons does oxygen have?

The valence electron the oxygen will certainly be 6. Due to the fact that when friend look at the electronic configuration that oxygen, there room 6 electrons current in the last cell(valence cell).

Problem7 How countless valence electrons do Fluorine have?

The valence electron of fluorine is 7. That is, fluorine will gain 1 electron and gain the electronic configuration the neon. And the valency the fluorine will be 1.

Problem8 How countless valence electron does Nitrogen have?

There are five electrons existing in the last cell that nitrogen. Thus, the valence electron of nitrogen will certainly be five.

Problem9 How numerous valence electrons carry out Sodium have?

The valence electron the sodium will be one. Since the last cell of sodium i.e. 3s has only one electron.


This accuse discusses how many valence electron there room in carbon. And also the valency the carbon is questioned in depth here. Here are some beautiful photos that have actually been included to the indict to make you understand.
