How Many Valence Electrons Does Hydrogen Have?

Answer:

Hydrogen has one valence electron.

Explanation:

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

             Step-1:

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

From periodic table ,we see that the atomic number of hydrogen is 1.

                 Step-2:

We know that the atomic number of hydrogen is 1.So hydrogen has 1 protons and 1 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 hydrogen.

H(1)=1s¹

                Step-4:

H(1)=1s¹

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

H(1)=1s¹

Valence shell can be found from the highest number of principal quantum number.You know that principal quantum number is expressed by n.
H(1)=1s¹

Here the highest value of n is 1.SoThe valence shell of hydrogen is 1s¹

                 Step-5

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

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

H(1)=1s¹

From the above electron 

configuration 

of hydrogen,we see 

that hydrogen has 1 

valence electron in its 

valence shell.

So there is one valence electron of hydrogen.
