How many valence electrons does tellurium have?

Answer:

Tellurium has six valence electrons.

Explanation:

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

The position of tellurium in the periodic table is in group VIA.For main group elements,valence electrons are equal to the group number.So,tellurium atom has six valence electrons in its valence shell or outermost energy level.

Again, tellurium 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 tellurium.

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

The symbol of tellurium is Te and the atomic number of tellurium is 52.So,it has fifty two  electrons totally.

Now write the electronic configuration of tellurium.

Te(52) =1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 4d10 5s2 5p4

=[Kr]4d10 5s2 5p4

             

[Tip: Complete filled d orbital is not considered as part of  valence shell or energy level]

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 5.So,the valence shell is the 5th shell or energy level.

In 5th shell,we get six valence electrons.So each tellurium has six valence electrons.
