How Many Valence Electrons Does Neon Have?

Answer:

Neon has eight valence electrons.

Explanation:

Now I am going to show you how many  valence electrons  neon have in just 5 steps.

             Step-1:

First, find the atomic number of neon from periodic table.

From periodic table ,we see that the atomic number of neon is 10.

                 Step-2:

We know that the atomic number of neon is 10.So neon has 10 protons and 10 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.

                Step-3:

Now write the electron configuration of neon .

Ne(10)=1s²2s²2p⁶

                Step-4:

Ne(10)=1s²2s²2p⁶

Now we will find out valence shell of neon from the electronic configuration of  neon.

Ne(13)=1s²2s²2p⁶

Valence shell can be found from the highest number of principal quantum number.

You know that principal quantum number is expressed by n.

Ne(10)=1s²2s²2p⁶

Here the highest value of n is 2.SoThe valence shell of neon is 2s²2p⁶

                 Step-5

In this step,we will find out the valence electrons of neon.

We have to know that the electrons of valence shell are called valence electrons.

Ne(10)=1s²2s²2p⁶

From the above electron 

configuration 

of neon,we see 

that neon has 8 

valence electrons in its 

valence shell(2s²2p⁶).

So there are eight valence electrons of neon.
