Explanation:

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

                   Step-1:

To do electron configuration of Ra element we have to know the atomic number of the Ra  element.The atomic number of Ra element is 88.So Ra element has 88 electrons and 88 protons.



Look how I find the electron configuration of Ra element.

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 numer 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.

Then....

              Step-5:


Now we know that Ra(Radium)  has 88 electrons.

Electron configuration of  Rn will be...


s² s²

p⁶s² p⁶s²

d¹ºp⁶s² d¹ºp⁶s²

f¹⁴d¹ºp⁶s² fdps fdps....

So,we are getting..



s² s²

p⁶s² p⁶s²

d¹ºp⁶s² d¹ºp⁶s²

f¹⁴d¹ºp⁶s² 


Now number s-orbital according  to above process.

1s² 2s²

p⁶3s² p⁶4s²

d¹ºp⁶5s² d¹ºp⁶6s²


f¹⁴d¹ºp⁶7s² 




Now number p-orbital according to above process.



1s² 2s²

2p⁶3s² 3p⁶4s²

d¹º4p⁶5s² d¹º5p⁶6s²



f¹⁴d¹º6p⁶7s² 

Now number d-orbital according to above process.



1s² 2s²

2p⁶3s² 3p⁶4s²

3d¹º4p⁶5s² 4d¹º5p⁶6s²




f¹⁴5d¹º6p⁶7s² 

Now we need to number f orbital.

1s² 2s²

2p⁶3s² 3p⁶4s²

3d¹º4p⁶5s² 4d¹º5p⁶6s²




4f¹⁴5d¹º6p⁶7s² 

In a line---

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹º 4p⁶ 5s² 4d¹º 5p⁶ 6s² 4f¹⁴ 5d¹º 6p⁶ 7s² 

So the Ra electron configuration  is given below:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹º 4p⁶ 5s² 4d¹º 5p⁶ 6s² 4f¹⁴ 5d¹º 6p⁶ 7s² 

  



Remember that the electronic configuration of any element is written in the assending (low to high) order of  n.Finally,the above electronic configuration should be written according to value of n as follows.

         
1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹º 4s² 4p⁶ 
4d¹º 4f¹⁴ 5s²5p⁶ 5d¹º6s² 6p⁶7s²


Radium Full Electron Configuration:

1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹º 4s² 4p⁶ 

4d¹º 4f¹⁴ 5s²5p⁶ 5d¹º6s² 6p⁶7s²

=Rn 7s2

Valence Electrons and shell of Radium:
