【5 Steps】Electron Configuration of Xe or for Xe in Just 5 Steps

Electron Configuration of Xe (Xenon) in Just 5 Steps

To do or find or writing electron configuration of  Xe (Xenon),we will follow just 5 steps.

                   Step-1:

To do electron configuration of Xe (Xenon),we have to know the atomic number of  Xe (Xenon).

The atomic number of Xe (Xenon) is 54.So it has 54 electrons and 54 protons.

Look how I find the electronic configuration of Xe (Xenon).
.

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 Xe (Xenon) has 54 electrons.

Electron configuration of  

Xe (Xenon)  will be...

s² s²

p⁶s² p⁶s²

d¹ºp⁶s² d¹ºp⁶s

fdps fdps fdps....

So,we are getting..

s² s²

p⁶s² p⁶s²

d¹ºp⁶s² d¹ºp⁶

Now number s-orbitals according  to above process.

1s² 2s²

p⁶3s² p⁶4s²

d¹ºp⁶5s² d¹ºp⁶

Now number the p orbitals according to above process.

1s² 2s²

2p⁶3s² 3p⁶4s²

d¹º4p⁶5s² d¹º5p⁶

Now number d orbitals according to above process......

1s² 2s²

2p⁶3s² 3p⁶4s²

3d¹º4p⁶5s² 4d¹º5p⁶

Now arrange this--low to high value of n

1s²2s²2p⁶3s²3p⁶ 3d¹º4s²4p⁶4d¹º5s²5p⁶

So the electron configuration of Xenon(Xe) is 

1s²2s²2p⁶3s²3p⁶ 3d¹º4s²4p⁶4d¹º5s²5p⁶
