The electronic configuration of potassium is 2,8,8,1.why does the last electron of potassium go to the fourth shell instead of occupying the third shell,even though the third shell has a capacity to accommodate ten more electrons.


ankurivup9fgqm: you read in which class ?
ishanaghosh: Ninth grade and you
ankurivup9fgqm: 11. the thing im telling is in 11th's chemistry chapter atomic structure
ishanaghosh: Okay. It's obvious then that I know the basics and you have studied in details..
ishanaghosh: It's just learning, isn't it
ankurivup9fgqm: yup.
ankurivup9fgqm: the beautiful learning
ankurivup9fgqm: Your confidence on knowledge impressed me. So, following you....
ishanaghosh: Thanks and I would like to follow you to if you would say how to

no it's capacity is 8 electrons in it in my opinion
hope it helps you

ankurivup9fgqm: sorry but you are wrong.
ishanaghosh: Yes you are wrong. 2n^2 formula is there for accommodation rules.
adkia: but it only needs 8 electronsto complete its octets ok
ankurivup9fgqm: @adkia you will find the proper answer soon I think. Just study carefully.

Electrons want to stay in less energy level. In this case the d orbital of 3rd shell carries more energy level than 4th Shell's s orbital.
That's why the last electron occupied the 4th shell instead of 3rd shell.
[Hope this helps]
For further knowledge search on youtube about shells and orbitals of an atom.

adkia: you are also wrong
ankurivup9fgqm: no mate. its in 11th's chemistry text book.
