If n=6 , the correct sequence for filling of electrons will be

Options

  1. An s (n-1) d (n-2) f n p
  2. Bn s (n-2) f n p (n-1) d
  3. Cn s n p (n-1) d (n-2) f
  4. Dn s (n-2) f (n-1) d n p

Correct answer

D. n s (n-2) f (n-1) d n p

Step-by-step solution

For n-6 olectron aro filled as 6 s 4 f 5 d 6 p This is because electron first enters in that orbitals for which (n+l) is lower. In case, if (n+I) is same, it goes first in that orbital for which n is lower.
