Many that you have actually this concern of how many electrons space in the last cell that carbon or how numerous valence electrons does carbon have?

In an easy words, the variety of electrons current in the valence covering (last electronic shell) is called valence electron.

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

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


Electronic configuration of Carbon

If friend look at the electronic configuration of carbon, you deserve to see that there room two cells present in carbon. The first cell has actually two electrons and the critical cell has 4 electrons. So look at this illustration that the electrical configuration the carbon.


Also, plenty of of you are confused in between the valency that carbon and valence electron. So, for this, you need to know the difference 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 secure state, the variety of electrons that leaves, or gain or common shares in order to fill its octet, us will speak to that facet the valence. Thus, the valency that carbon is four.


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

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

There are some aspects that deserve to neither get nor lose electrons in your last cell. In order for this element to be stable, the electrons in its critical cell need to be mutually shared 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 electron in the last cell in order to get its stability. Since in this case, you have actually to offer a lot of energy. For this, carbon constantly 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 completely discussed below.

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

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

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

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

Problem3 What is the valency electron of oxide ion?

If girlfriend look in ~ the electronic configuration that oxide ions, you can see the there space 8 electrons existing in the valence cell. Thus, the valency electron of oxide ion is 8.

Problem4 Give instances of facets other 보다 carbon whose valency and valence electrons will certainly 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 elements that have more than one valence.

Such together iron. It has actually two valences, two and also three. Steel will shed two electrons at some suggest and turn into rt and also at an additional time it will lose three electrons and turn right into py. There are additionally many aspects that have more than one valence.

Problem6 How plenty of valence electrons does oxygen have?

The valence electron of oxygen will be 6. Because when you look in ~ the electronic configuration the oxygen, there space 6 electrons present in the critical cell(valence cell).

Problem7 How many valence electrons do Fluorine have?

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

Problem8 How plenty of valence electron does Nitrogen have?

There are 5 electrons existing in the last cell that nitrogen. Thus, the valence electron of nitrogen will be five.

Problem9 How numerous valence electrons execute Sodium have?

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


This indict discusses how countless valence electron there space in carbon. And also the valency that carbon is questioned in depth here. Right here are some beautiful photos that have actually been added to the accuse to make you understand.
