【】How Many Valence Electrons Does Fluorine(F) Have?|fluorine valence electrons

Answer:

Fluorine (F) has seven valence electrons.

Explanation:

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

             Step-1:

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

From periodic table ,we see that the atomic number of fluorine is 9.

                 Step-2:

We know that the atomic number of fluorine is 9.So fluorine has 9 protons and 9 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 fluorine. 

F(9)=1s²2s²2p⁵

                Step-4:

F(9)=1s²2s²2p⁵

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

F(9)=1s²2s²2p⁵

Valence shell can be found from the highest number of principal quantum number.You know that principal quantum number is expressed by n.

F(9)=1s²2s²2p⁵

Here the highest value of n is 2.SoThe valence shell of fluorine is 2s²2p⁵

                 Step-5

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

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

F(9)=1s²2s²2p⁵

From the above electron 

configuration 

of fluorine,we see 

that fluorine has 7 

valence electron in its 

valence shell.

So there are seven valence electrons of fluorine.
