Question

sodium ion has completely filled k and l shells explain ​

Answer 1

Answer:

Atomic no. of Na+ = 11

  configuration =  K   L   M

                           = 2    8    1        

Hence because it has an atomic no. of 11 it has completed it's k % L shell also                      k = 2(n)^2=  2 (1)^2 = 2

                             l = 2(n)^2 = 2(2)^2 = 8

          their limits of e-
