Many of you have this question of how numerous electrons room in the last cell that carbon or how numerous valence electron does carbon have?

In an easy words, the variety of electrons current in the valence covering (last digital shell) is referred to as valence electron.

You are watching: How many valence electrons does carbon

The over two questions median the very same thing, so the carbon has four valence electrons. The is, there are 4 electrons existing in the critical cell of carbon.


Electronic construction of Carbon

If girlfriend look in ~ the electronic configuration the carbon, you have the right to see the there room two cells current in carbon. The an initial cell has actually two electrons and also the critical cell has four electrons. So look in ~ this illustration that the electrical configuration that carbon.


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

What is Valancy the Carbon

According to the octet theory, in order for each element to reach a stable state, the variety of electrons it leaves, or acquire or common shares in order to to fill its octet, us will contact that facet the valence. Thus, the valency of carbon is four.


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

Many that you might be confused regarding where the word shared share in meaning came from.

There are some facets that have the right to neither gain nor lose electrons in your last cell. In order for this aspect to it is in stable, the electrons in its critical cell have to be mutually common with other elements.


An instance is a carbon. Due to the fact that it never ever becomes a c-4 or c+4 ion by accepting or rejecting the 4 electron in the critical cell in bespeak to acquire its stability. Because in this case, you have actually to offer a lot of energy. For this, carbon constantly forms covalent binding by mutually sharing its very own 4 electrons.


Question prize on valency and also valence electrons

The question-and-answer on valence and also valence electron is totally discussed below.

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

Valence electrons have actually no relation with Valency. Both are various concepts. Will be same in the instance of those elements whose number of electrons in the last cell will certainly be equal to the number of electrons obtained or rejected because that the stability of that element. Such together carbon, hydrogen, etc.

Problem2 What is the electron valency that neon and also how countless electrons are current in its last cell?

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

Problem3 What is the valency electron the oxide ion?

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

Problem4 Give examples of aspects other 보다 carbon who valency and valence electrons will be equal.

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

Problem5 Give examples of aspects that have an ext than one valence.

Such as iron. It has two valences, two and also three. Stole will lose two electron at some suggest and turn right into rt and at another time the will lose three electrons and turn into py. Over there are additionally many facets that have more than one valence.

Problem6 How many valence electrons does oxygen have?

The valence electron that oxygen will certainly be 6. Due to the fact that when you look in ~ the digital configuration that oxygen, there room 6 electrons present in the critical cell(valence cell).

Problem7 How countless valence electrons carry out Fluorine have?

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

Problem8 How plenty of valence electrons does Nitrogen have?

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

Problem9 How many valence electrons perform Sodium have?

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


This tutorial discusses how countless valence electron there are in carbon. And also the valency of carbon is discussed in depth here. Below are part beautiful picture that have actually been added to the indict to do you understand.
