Electron Configuration Chart for Chlorine,Cl

Explanation:

Here is the way you can follow to write the electron configuration of chlorine in just 5 steps.

                   Step-1:
To do electronic configuration of chlorine,we have to know the atomic number of chlorine.

The atomic number of chlorine is 17.So chlorine has 17 electrons and 17 protons.

Look how I find the electronic configuration for chlorine(Cl).

This process is applicable for all the elements of the periodic table.

                     
                      Step-2:

(How do you remember the order of electron configurations?)


Now we have to memorize the following sequence of the orbitals.

ss   

ps ps 

dps  dps   

fdps fdps fdps fdps....


In a line-

ss ps ps dps dps fdps fdps 

fdps fdps fdps fdps.......               

  Step-3:

Now we have to first number the s-orbital (start with 1s)like this:

1s2s  

p3s   p 4s

dp 5s  dp 6s


fdp7s  fdp 8s...... According to your need.


In a line-

1s2s  p3s   p 4s dp 5s  dp 6s

fdp7s  fdp 8s........

Remember
                   ● s-orbital start with 1s

                  ●   p-orbital start with 2p
                   
                   ●  d-orbital start with 3d
                   ● f-orbital start with 4f

Again,Now(second) we need  number the p-orbital(start with 2p) like this:


ss   

2ps  3ps 

d 4ps   d 5ps   

fd6ps fd7ps fd8ps fd9ps....


In a line--


ss  2ps  3ps  d4ps   d5ps   

fd6ps fd7ps fd8ps fd9ps....

Thirdly,we need number the d-orbital(start with 3d)like this:



ss   

ps ps 

3dps  4dps   

f5dps f6dps f7dps f8dps....



In a line--


ss ps ps 3dps  4dps  

 f5dps f6dps f7dps f8dps....

Fourthly,number the f-orbital(start with 4f) like this:

ss   

ps ps 

dps  dps   

4fdps  5fdps 6fdps 7fdps....


In a line--


ss  ps ps dps  dps  4fdps  5fdps 6fdps 7fdps......

Fifltly,number s,p,d,f together like this....

1s2s

2p3s   3p4s

3d4p5s 4d5p6s


4f5d6p7s  5f6d7p8s 

6f7d8p9s.........



In a line----

1s 2s 2p 3s 3p 4s 3d 4p 5s d 5p 6s 4f 5d 6p 7s 5f 6d 7p 8s 
6f 7d 8p 9s.........

How do you remember the order of electron configurations?

               Step-4:
(What is spdf in electron configuration?
think--)

Now we have to know that

•S-orbital can take maximum 2 electrons.

•p-orbital can take maximum 6 electrons.

•d-orbital can take maximum 10 electrons.

•f-orbital can take  maximum 14 electrons.

              Step-5:


Now we know that Cl   has 16 electrons.

Electronic configuration of  Chlorine (Cl)will be...


s² s²

p⁶s² p⁵s

dps dps

fdps fdps fdps....

So,we are getting..



s² s²

p⁶s² p⁵

Now number s-orbital according  to above process.

1s² 2s²

p⁶3s² p⁵

Now number p-orbital according to above process.



1s² 2s²

2p⁶3s² 3p⁵

So the electronic configuration for  chlorine  is given below:

1s² 2s² 2p⁶ 3s² 3p⁵

Abbreviated electron configuration for chlorine: 

[Ne] 3s² 3p⁵

 ●What is the electron configuration of chlorine(Cl)?
