Electron Configuration of Iron(Fe)
Now we are going to reveal how to do or find electron configuration or write electronic configuration of iron (Fe).To do or find or write electronic configuration for iron (Fe),we will follow just 5 steps.
Step-1:
To do electron configuration of iron,we have to know the atomic number of the iron(Fe).
The atomic number of iron is 26.So iron has 26 electrons and 26 protons.Look how I find the electron configuration of this iron.This process is applicable for all the elements of the periodic table.
Step-2:
Now to do electronic configuration of iron, we are bound 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

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 to Do Electron Configuration of Fe
Step-4:
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 iron has 26 electrons.
Electron configuration of iron will be...
s² s²
p⁶s² p⁶s²
d⁶ps dps
fdps fdps fdps....
So,we are getting..
s² s²
p⁶s² p⁶s²
d⁶
Now number s-orbital according to above process.
1s² 2s²
p⁶ 3s² p⁶ 4s²
d⁶
Now number p-orbital according to above process.
1s² 2s²
2p⁶ 3s² 3p⁶ 4s²
d⁶
Now number d-orbital according to above process.
1s² 2s²
2p⁶ 3s² 3p⁶ 4s²
3d⁶
In a line---
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶
So the electronic configuration of Iron(Fe) is given below:
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶
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.
