Many the you have this concern of how many electrons are in the critical cell the carbon or how countless valence electron does carbon have?
In simple words, the variety of electrons present in the valence shell (last electronic shell) is dubbed valence electron.
You are watching: What is the valence electron of carbon
The above two questions average the same thing, for this reason the carbon has four valence electrons. That is, there are 4 electrons present in the critical cell of carbon.
Electronic configuration of Carbon
If girlfriend look at the digital configuration that carbon, you can see the there room two cells present in carbon. The an initial cell has actually two electrons and the critical cell has four electrons. For this reason look in ~ this illustration of the electrical configuration that carbon.
Also, numerous of you room confused between the valency the carbon and valence electron. So, because that this, you need to know the difference between valency and valence electrons.
What is Valancy the Carbon
According to the octet theory, in order because that each facet to with a secure state, the variety of electrons the leaves, or obtain or shared shares in stimulate to to fill its octet, we will speak to that element the valence. Thus, the valency that carbon is four.
After each aspect gains stability, its electronic configuration will certainly be favor the nearest Nobel gas.
Many of you might be confused regarding where the word common share in meaning came from.
There room some elements that can neither obtain nor lose electrons in their last cell. In order for this facet to be stable, the electrons in its last cell have to be mutually shared with various other elements.
An instance 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 stimulate to obtain its stability. Because in this case, you have actually to offer a lot of energy. For this, carbon always forms covalent bonds by mutually share its own 4 electrons.
Question price on valency and valence electrons
The question-and-answer ~ above valence and valence electrons is fully discussed below.
Problem1 In the situation of carbon, valency, and also valence electrons are equal. So will certainly valence and valence electrons 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 facets whose number of electrons in the critical cell will be equal to the number of electrons received or rejected because that the stability of the element. Such as carbon, hydrogen, etc.
Problem2 What is the electron valency the neon and how plenty of electrons are existing in its critical cell?
Neon is an inert element. The is, the neon will certainly not get or reject any kind of electrons. In this case, the valency of neon will be zero. And also the last cell that neon will always have 8 electrons. Thus, octet will remain met. The valency electron the neon will be 8.
Problem3 What is the valency electron of oxide ion?
If you look at the digital configuration of oxide ions, you can see the there space 8 electrons current in the valence cell. Thus, the valency electron the oxide ion is 8.
Problem4 Give examples of facets other than carbon whose valency and also valence electrons will be equal.
The valence the the hydrogen and the valence electron will both be equal. Hydrogen’s valence electron will certainly be 1.
Problem5 Give examples of elements that have an ext than one valence.
Such as iron. It has actually two valences, two and also three. Iron will lose two electron at some point and turn into rt and at an additional time it will lose three electrons and turn into py. There are additionally many facets that have an ext 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 you look at the digital configuration of oxygen, there room 6 electrons existing in the last cell(valence cell).
Problem7 How many valence electrons do Fluorine have?
The valence electron of fluorine is 7. The is, fluorine will gain 1 electron and also gain the digital configuration that neon. And also the valency of fluorine will certainly be 1.
Problem8 How numerous valence electron does Nitrogen have?
There are 5 electrons present in the critical cell that nitrogen. Thus, the valence electron that nitrogen will be five.
Problem9 How numerous valence electrons do Sodium have?
The valence electron that sodium will certainly be one. Because the critical cell of sodium i.e. 3s has only one electron.
This indict discusses how numerous valence electrons there room in carbon. And also the valency that carbon is discussed in depth here. Right here are part beautiful picture that have been included to the accuse to make you understand.
