【】How Many Valence Electrons Does Oxygen Have?||number of valence electrons in oxygen

Oxygen has six valence electrons.

Explanation:

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

             Step-1:

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

From periodic table ,we see that the atomic number of oxygen is 8.

                 Step-2:

We know that the atomic number of oxygen is 8.So oxygen has 8 protons and 8electrons 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  oxygen.

O(8)=1s²2s²2p⁴

                Step-4:

O(8)=1s²2s²2p⁴

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

O(8)=1s²2s²2p⁴

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

O(8)=1s²2s²2p⁴

Here the highest value of n is 2.SoThe valence shell of oxygen is 2s²2p⁴.

                 Step-5

In this step,we will find out the valence electrons of oxygen.We have to know that the electrons of valence shell are called valence electrons. 


O(8)=1s²2s²2p⁴

From the above electron configuration of oxygen,we see that oxygen has 6 valence electrons in its valence shell.

So there are 6 valence electrons of oxygen.
