Periodic Table of Elements with Valence Electrons Trends. In the below periodic table you can see the trend of Valence Electrons. For facts, physical properties, chemical properties, structure and atomic properties of the specific element, click on the element symbol in the below periodic table. Transcript: This is the CBr4 Lewis structure: Carbon Tetrabromide. Carbon is in group 4 or 14, so it has 4 valence electrons. Bromine in group 7 or 17, so it has 7, and we have 4 Bromines. So 4 plus 28 equals 32 total valence electrons. Carbon, that's the least electronegative, that'll go in the center; and on the outside we'll put the Bromine.

Many of you have this question of how many electrons are in the last cell of carbon or how many valence electrons does carbon have?
In simple words, the number of electrons present in the valence shell (last electronic shell) is called valence electron.
The above two questions mean the same thing, so the carbon has four valence electrons. That is, there are 4 electrons present in the last cell of carbon.
Electronic Configuration of Carbon
If you look at the electronic configuration of carbon, you can see that there are two cells present in carbon. The first cell has two electrons and the last cell has four electrons. So look at this illustration of the electric configuration of carbon.
Also, many of you are confused between the valency of carbon and valence electron. So, for this, you need to understand the difference between valency and valence electrons.
What is Valancy of Carbon
According to the octet theory, in order for each element to reach a stable state, the number of electrons it leaves, or gain or mutual shares in order to fill its octet, we will call that element the valence. Thus, the valency of carbon is four.
After each element gains stability, its electronic configuration will be like the nearest Nobel gas.
Many of you may be confused as to where the word mutual share in definition came from.
There are some elements that can neither gain nor lose electrons in their last cell. In order for this element to be stable, the electrons in its last cell have to be mutually shared with other elements.
An example is a carbon. Because it never becomes a c-4or c+4ion by accepting or rejecting the 4 electrons in the last cell in order to gain its stability. Because in this case, you have to give a lot of energy. For this, carbon always forms covalent bonds by mutually sharing its own 4 electrons.
Question Answer on valency and valence electrons
The question-and-answer on valence and valence electrons is fully discussed below.
Problem1In the case of carbon, valency, and valence electrons are equal. So will valence and valence electrons be equal or different in case of all other elements?
Valence electrons have no relation with Valency. Both are different concepts. Will be equal in the case of those elements whose number of electrons in the last cell will be equal to the number of electrons received or rejected for the stability of that element. Such as carbon, hydrogen, etc.
Problem2What is the electron valency of neon and how many electrons are present in its last cell?
Neon is an inert element. That is, the neon will not receive or reject any electrons. In this case, the valency of neon will be zero. And the last cell of neon will always have 8 electrons. Thus, octet will remain met. The valency electron of neon will be 8.
Problem3What is the valency electron of oxide ion?
If you look at the electronic configuration of oxide ions, you can see that there are 8 electrons present in the valence cell. Thus, the valency electron of oxide ion is 8.
Problem4Give examples of elements other than carbon whose valency and valence electrons will be equal.
The valence of the hydrogen and the valence electron will both be equal. Hydrogen’s valence electron will be 1.
Problem5Give examples of elements that have more than one valence.
Such as iron. It has two valences, two and three. Iron will lose two electrons at some point and turn into rt and at another time it will lose three electrons and turn into py. There are also many elements that have more than one valence.
Problem6How many valence electrons does oxygen have?
The valence electron of oxygen will be 6. Because when you look at the electronic configuration of oxygen, there are 6 electrons present in the last cell(valence cell).
Problem7How many valence electrons do Fluorine have?
The valence electron of fluorine is 7. That is, fluorine will gain 1 electron and gain the electronic configuration of neon. And the valency of fluorine will be 1.
Problem8How many valence electrons does Nitrogen have?
There are five electrons present in the last cell of nitrogen. Thus, the valence electron of nitrogen will be five.
Problem9How many valence electrons do Sodium have?
The valence electron of sodium will be one. Because the last cell of sodium i.e. 3s has only one electron.
Conclusion
This tutorial discusses how many valence electrons there are in carbon. And also the valency of carbon is discussed in depth here. Here are some beautiful photos that have been added to the tutorial to make you understand.
So, if we can add any value to your life with the help of this tutorial, then you must share this post.
