Electron configuration chart for Krypton(Kr)

Explanation:

Here is the way you can follow to write the electron configuration of  Krypton(Kr) in just 5 steps.

                Step-1:

To do electron configuration of krypton(Kr),we have to know the atomic number of  Krypton(Kr).

The atomic number of krypton(Kr) is 36.So it has 36 electrons and 36 protons.

Look how I find the electronic configuration of krypton(Kr).

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 krypton has 36 electrons.

Electronic configuration of  

Krypton(Kr)  will be...

s² s²

p⁶s² p⁶s²

d¹ºp⁶s dps

fdps fdps fdps....

So,we are getting..

s² s²

p⁶s² p⁶s²

d¹ºp⁶

Now number s-orbital according  to above process.

1s² 2s²

p⁶3s² p⁶4s²

d¹ºp⁶

Now number p -orbital according to above process.

1s² 2s²

2p⁶3s² 3p⁶4s²

d¹º4p⁶

Now number d-orbital.....

1s² 2s²

2p⁶3s² 3p⁶4s²

3d¹º4p⁶

At last,you have to arrange the above things in the ascending order of n(low to high)

1s² 2s²2p⁶3s² 3p⁶ 3d¹º4s²4p⁶

So the electron configuration of  krypton(Kr)  is given below:

1s² 2s²2p⁶3s² 3p⁶ 3d¹º4s²4p⁶
