Many of you have actually this question of how numerous electrons room in the critical cell that carbon or how many valence electrons does carbon have?

In straightforward words, the variety of electrons present in the valence covering (last electronic shell) is called valence electron.

You are watching: How many valence electrons does a carbon atom have?

The over two questions typical the same thing, for this reason the carbon has four valence electrons. That is, there are 4 electrons present in the last cell the carbon.


Electronic construction of Carbon

If you look in ~ the electronic configuration that carbon, you can see the there room two cells present in carbon. The first cell has two electrons and also the critical cell has four electrons. Therefore look at this illustration the the electrical configuration of carbon.


Also, countless of you room confused between the valency the carbon and also valence electron. So, for this, you need to recognize the difference in between valency and valence electrons.

What is Valancy of Carbon

According to the octet theory, in order because that each facet to reach a secure state, the variety of electrons the leaves, or obtain or mutual shares in order to to fill its octet, we will call that element the valence. Thus, the valency the carbon is four.


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

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

There are some aspects that have the right to neither get nor shed electrons in their last cell. In order for this element to it is in stable, the electrons in its last cell have to be mutually shared with other elements.


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


Question prize on valency and also valence electrons

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

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

Valence electrons have actually no relation with Valency. Both are different concepts. Will certainly be equal in the case of those aspects whose variety of electrons in the last cell will certainly be same to the variety of electrons received or rejected because that the security of the element. Such together carbon, hydrogen, etc.

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

Neon is an inert element. That is, the neon will certainly not get or reject any electrons. In this case, the valency of neon will certainly be zero. And also the last cell that neon will always have 8 electrons. Thus, octet will continue to be met. The valency electron of neon will be 8.

Problem3 What is the valency electron that oxide ion?

If friend look in ~ the digital configuration the oxide ions, you can see the there are 8 electrons existing in the valence cell. Thus, the valency electron of oxide ion is 8.

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

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

Problem5 Give examples of elements that have much more than one valence.

Such together iron. It has actually two valences, two and also three. Iron will lose two electrons at some suggest and turn into rt and at one more time it will lose three electrons and also turn into py. Over there are also many aspects that have an ext than one valence.

Problem6 How numerous valence electrons does oxygen have?

The valence electron that oxygen will certainly be 6. Due to the fact that when girlfriend look at the digital configuration the oxygen, there are 6 electrons existing in the last cell(valence cell).

Problem7 How countless valence electrons carry out Fluorine have?

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

Problem8 How many valence electron does Nitrogen have?

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

Problem9 How many valence electrons execute Sodium have?

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


This tutorial discusses how many valence electrons there space in carbon. And likewise the valency of carbon is questioned in depth here. Right here are part beautiful picture that have been included to the tutorial to do you understand.
