"How to remember electro-negativity series? Are there any easy ways to remember it?" you may ask a question like that.

Yes indeed! There is!
I used to remember the electro-negativity series using a
 mnemonic method. Well don't be confused of the word "mnemonic". Mostly you would have studied and memorised periodic table in O/L in the way of mnemonic (Eg: Hi Henry Listen B....).

Mnemonic method is awesome because, those things we study using this technique, we rarely forget them.


Well I'll come to the point. This is how I remembered electro-negativity series.
"(Ph)FON(e) C(h)l(orine) Br(omin) Iodin SCPH".

I remembered it as a song. "FON Clorine Bromine Iodine SCPH".
In this song,

Well now you may ask me that "Nitrogen or Chlorine, which's electro-negativity is higher?". You may ask this question because your teacher would have taught that Cl is more electrically negative than N , but I'm telling you vise verse

Well this is a common problem among students. In above table, just see the value of electro negativity of Chlorine and Nitrogen. Both are (nearly) equal and the Pualings electro-negativity value is 3.0 . Because of the nearly equal value, most of students get a doubt in electro negativity order....

You can trust me and memorise this "FON Clorin Bromin Iodin SCPH"

Or you can just trust your teacher and make a new way to remember it.
