Many of you have actually this question of how numerous electrons space in the critical cell that carbon or how plenty of valence electrons does carbon have?
In simple words, the variety of electrons current in the valence shell (last electronic shell) is called valence electron.
You are watching: How many valence electrons are in a carbon atom
The above two questions typical the exact same thing, so the carbon has 4 valence electrons. That is, there room 4 electrons existing in the last cell that carbon.
Electronic construction of Carbon
If friend look at the electronic configuration that carbon, you can see that there room two cells present in carbon. The an initial cell has actually two electrons and also the last cell has four electrons. Therefore look in ~ this illustration the the electric configuration of carbon.
Also, many of you space confused between the valency the carbon and valence electron. So, because that this, you need to recognize the difference between valency and also valence electrons.
What is Valancy of Carbon
According come the octet theory, in order because that each aspect to reach a stable state, the variety of electrons it leaves, or get or shared shares in bespeak to to fill its octet, us will contact that element the valence. Thus, the valency that carbon is four.
After each aspect gains stability, its electronic configuration will be like the nearest Nobel gas.
Many the you may be confused as to where the word shared share in an interpretation came from.
There room some facets that can neither get nor lose electrons in their last cell. In order because that this facet to it is in stable, the electron in its critical cell need to be mutually mutual with other elements.
An example 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 last cell in bespeak to obtain its stability. Because in this case, you have actually to offer a many energy. For this, carbon always forms covalent bonds by mutually share its very own 4 electrons.
Question price on valency and valence electrons
The question-and-answer on valence and valence electrons is totally discussed below.
Problem1 In the case of carbon, valency, and valence electrons are equal. So will valence and valence electrons be equal or different in situation of all various other elements?
Valence electrons have actually no relation v Valency. Both are different concepts. Will certainly be equal in the situation of those elements whose variety of electrons in the last cell will certainly be same to the number of electrons obtained or rejected for the stability of the element. Such as carbon, hydrogen, etc.
Problem2 What is the electron valency that neon and how numerous electrons are present in its last cell?
Neon is one inert element. The is, the neon will certainly not obtain or reject any type of electrons. In this case, the valency that neon will certainly be zero. And also the critical cell of neon will always have 8 electrons. Thus, octet will stay met. The valency electron of neon will certainly be 8.
Problem3 What is the valency electron that oxide ion?
If friend look in ~ the electronic configuration of oxide ions, you have the right to see that there are 8 electrons present in the valence cell. Thus, the valency electron the oxide ion is 8.
Problem4 Give instances of aspects other than carbon who valency and valence electrons will be equal.
The valence that 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 elements that have much more than one valence.
Such as iron. It has two valences, two and also three. Iron will lose two electrons at some allude and turn right into rt and at an additional time the will lose three electrons and also turn right into py. There are likewise many elements that have an ext than one valence.
Problem6 How plenty of valence electron does oxygen have?
The valence electron of oxygen will be 6. Due to the fact that when girlfriend look in ~ the electronic configuration that oxygen, there space 6 electrons present in the critical cell(valence cell).
Problem7 How countless valence electrons perform Fluorine have?
The valence electron the fluorine is 7. That is, fluorine will obtain 1 electron and gain the digital configuration that neon. And the valency of fluorine will certainly be 1.
Problem8 How numerous valence electrons does Nitrogen have?
There are five electrons existing in the last cell that nitrogen. Thus, the valence electron of nitrogen will certainly be five.
Problem9 How numerous valence electrons perform Sodium have?
The valence electron the sodium will certainly be one. Due to the fact that the last cell of sodium 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 debated in depth here. Here are some beautiful image that have actually been included to the tutorial to make you understand.
