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

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

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

The above two questions median the exact same thing, therefore the carbon has 4 valence electrons. The is, there space 4 electrons existing in the critical cell the carbon.


Electronic configuration of Carbon

If girlfriend look in ~ the digital configuration that carbon, you can see the there are two cells present in carbon. The very first cell has actually two electrons and also the critical cell has 4 electrons. Therefore look in ~ this illustration that the electric configuration the carbon.


Also, many of you are confused between the valency the carbon and valence electron. So, because that this, you need to understand the difference in between valency and also valence electrons.

What is Valancy that Carbon

According to the octet theory, in order because that each aspect to with a stable state, the variety of electrons that leaves, or obtain or shared shares in order to to fill its octet, we will contact that element the valence. Thus, the valency of carbon is four.


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

Many of you might be confused regarding where the word common share in an interpretation came from.

There space some aspects that have the right to neither obtain nor lose electrons in your last cell. In order because that this facet to be stable, the electron in its last cell have to be mutually common with various other elements.


An instance is a carbon. Because it never becomes a c-4 or c+4 ion by accepting or rejecting the 4 electrons in the critical cell in stimulate to acquire its stability. Since in this case, you have actually to offer a many energy. For this, carbon constantly forms covalent bonds by mutually share its own 4 electrons.


Question price on valency and valence electrons

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

Problem1 In the case of carbon, valency, and valence electrons space equal. So will certainly valence and valence electron be same or various in instance of all other elements?

Valence electrons have no relation v Valency. Both are different concepts. Will be same in the case of those elements whose number of electrons in the last cell will be same to the number of electrons got or rejected for the security of the element. Such together carbon, hydrogen, etc.

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

Neon is one inert element. That is, the neon will not receive or reject any type of electrons. In this case, the valency that neon will certainly be zero. And the critical cell the neon will constantly have 8 electrons. Thus, octet will continue to be met. The valency electron that neon will be 8.

Problem3 What is the valency electron of oxide ion?

If you look at the electronic configuration of oxide ions, you can see the there room 8 electrons present in the valence cell. Thus, the valency electron of oxide ion is 8.

Problem4 Give examples of elements other than carbon whose valency and valence electrons will be equal.

The valence of the hydrogen and also the valence electron will both it is in equal. Hydrogen’s valence electron will certainly be 1.

Problem5 Give instances of facets that have more than one valence.

Such together iron. It has two valences, two and three. Stole will lose two electron at some point and turn right into rt and at one more time it will lose three electrons and turn into py. There are likewise many elements that have much more than one valence.

Problem6 How countless valence electron does oxygen have?

The valence electron the oxygen will be 6. Because when you look at the digital configuration that oxygen, there room 6 electrons existing in the critical cell(valence cell).

Problem7 How countless valence electrons do Fluorine have?

The valence electron the fluorine is 7. That is, fluorine will acquire 1 electron and gain the digital configuration that neon. And also the valency the fluorine will certainly be 1.

Problem8 How numerous valence electrons does Nitrogen have?

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

Problem9 How plenty of valence electrons carry out Sodium have?

The valence electron the sodium will certainly be one. Since the critical cell of salt i.e. 3s has actually only one electron.


This tutorial discusses how numerous valence electrons there space in carbon. And additionally the valency the carbon is debated in depth here. Here are some beautiful picture that have been included to the indict to make you understand.
