How Many Valence Electrons Does Nitrogen Have?

Answer:

Nitrogen has five valence electrons.

Explanation:

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

             Step-1:

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

From periodic table ,we see that the atomic number of nitrogen is 7.

                 Step-2:

We know that the atomic number of nitrogen is 7.So nitrogen has 7 protons and 7 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  nitrogen.

N(7)=1s²2s²2p³

                Step-4:

N(7)=1s²2s²2p³

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

N(7)=1s²2s²2p³

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

N(7)=1s²2s²2p⁵

Here the highest value of n is 2.SoThe valence shell of nitrogen is 2s²2p³.

                 Step-5

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


N(7)=1s²2s²2p³

From the above electron configuration of nitrogen,we see that nitrogen has 5 valence electrons in its valence shell.

So there are 5 valence electrons of nitrogen.
