Why electronic configuration of potassium is 2,8,8,1 instead of 2,8,9?

Question

Answer

Hey .......all shell don't carry 8 electrons in it only L and M carry 8 electrons and K shell carry 2 electron .......got it

Answer

Capacity of that shell is just 8 and to find the no.of electrons to be filled in the shell we use formula 2n^2 here ni is principle quantum number

Answer

Because in the third shell 'M', there can be  only 8 electrons so the the rest one have to go in the fourth shell 'N'

Answer

Bcz the capacity of M shell is to carry 8 electrons.........

Answer

Because every shell has a capacity os only 8 electron

Answer

Bcz none of orbital can carry 8+ electrons

Answer

Because E.C rule is that in the outermost shell only 8 electrons can stay so that's why potassium E.C is 2,8,8,1

Answer

Gud

Answer

Madhuri not all shells carry 8 electrons only L and M carry out 8 electron and K carry 2shell electrons
