How many valence electrons does sulfur have?
Answer:
Sulfur has six valence electrons.
To find out the number of valence electrons in a sulfur atom,we need to look at the periodic table.
The position of sulfur in the periodic table is in group VIA.For main group elements,valence electrons are equal to the group number.So,sulfur atom has six valence electrons in its valence shell.
Sulfur is an element of group 16.Now just consider the unit place digit from group number.You are getting 6 which is equal to the number of valence electrons in sulfur.
Here is the another way to find out the valence electrons of sulfur.
The symbol of sulfur is S and the atomic number of sulfur is 16.So,it has sixteen electrons totally.
Now do the electronic configuration of sulfur.
S(16) =1s2 2s2 2p6 3s2 3p4
=[Ne] 3s2 3p4
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 3.So,the valence shell is the 3rd shell.
In 3rd shell ,we get six valence electrons.So each sulfur has six valence electrons.
