Expert Answer:

Number of electrons in a shell=2(n2)
Value of n in K,L,M,N is 1,2,3,4
T o t a l space n u m b e r space o f space e l e c t r o n s space i n space a t o m equals 2 left parenthesis 1 squared right parenthesis plus 2 left parenthesis 2 squared right parenthesis plus 2 left parenthesis 3 squared right parenthesis plus 2 left parenthesis 4 squared right parenthesis space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 2 plus 8 plus 18 plus 32 space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 60
