How many valence electrons does carbon have?

How many valence electrons does carbon have?



Explanation:

C atom has four valence electrons.These electrons are important for carbon to form bonds with other atoms.

To find out the number of valence electrons in a C atom,we need to look at the periodic table.

The position of C in the periodic table  is in group IVA.For main group elements,valence electrons are equal to the group number.So a carbon atom has four valence electrons in its valence shell.

C is an element of group 14.Now just consider the unit place digit from group number.You are getting 4 which is equal to the number of valence electrons in carbon.


Here is the another way to find out the valence electrons of C.

The atomic number of C is 6.So it has six electrons totally.

Now do the electronic configuration of carbon.

C(6) =1s2 2s2 2p2

The valence shell is the outermost shell and the electrons that are present in valence shell is called valence electrons.

The valence shell or energy level can be identified by the highest value of principal quantum number ,n.Here the highest value of n is 2.So,the valence shell is the 2nd shell.

In 2nd shell we get 4 valence electrons.So  each C has 4 valence electrons.

Selenium has six valence electrons. Read:CO2 Lewis Structure Explanation: Now I am going to show you how to find valence electrons in selenium  in just 5 steps. Add caption              Step-1: First, find the atomic number of  selenium  from periodic table. From periodic table ,we see that the atomic number of  selenium  is 34.                  Step-2: We know that the atomic number of  selenium  is 34.So  selenium  has 34 protons and 34 electrons as the charge of electrons and protons are equal but opposite in nature.The charge of proton is +1 and the charge of electron is -1. Read:CO2 Lewis Structure                 Step-3: Now write the electron configuration of  selenium   . Se(34)=1s²2s²2p⁶3s²3p⁶4s²3d¹º4p⁴ Rewrite this from low to high value of n.

SO2 Lewis Structure   Answer: Here is the definition of SO2 Lewis structure. SO2 Lewis structure (sulfur dioxide electron dot structure) is that type of diagram where we show the total 18 valence electrons of SO2 as dots , or dots and dashes(-).In Lewis structure,it is common that a bonding pair of two electrons can be shown by  dash(-) or dots(●●) but a lone pair of two electrons is shown by dots[●●]. In SO2 Lewis structure,there are two double bonds that are going from the atom sulphur to oxygens. In SO2 Lewis structure ,there are totally five lone pairs of electrons.The each  oxygen has two lone pairs of electrons and the sulphur atom has one lone pair of electrons. In SO2 Lewis structure ,the oxygen atoms follow the octet rule but the sulfur atom don't follow the octet rule.It has more than eight electrons. In SO2 Lewis structure,we get nine pairs of electrons.Out of nine pairs of electrons,SO2 has four bond pairs of electrons and five lone pairs of electrons.Here,each oxy
