Each column in the Periodic Table represents a group of elements. All elements in a column have the same number of valence electrons but in different energy levels. From the above periodic table, one can easily find out the valence electron of the carbon atom. Carbon atom belongs to group 14 in which all elements have 4 valence electrons.

To find how many valence electrons are in an atom, you can look at the periodic table :. Look at the writing above each Group, or column.
The number next to the "A" is the number of valence electrons in an atom of an element in that Group. How many valence electrons are in carbon? Mar 12, Explanation: To find how many valence electrons are in an atom, you can look at the periodic table : Look at the writing above each Group, or column.
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. 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. 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.
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 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.
Problem1 In 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.
