Question
IF n & l are principle & azimuthal quantum no. respectively then expression for calculating total no. of e- in any energy level is?
summation from l=0 to n-1 (2(2l+1)) HOW
Joshi sir comment
for nth level values of l will be 0, 1, 2, 3, 4, 5, .....................(n-1)
for l = 0 means s subshell no. of electrons = 2 = 2(2*0+1)
for l = 1 means p subshell no. of electrons = 6 = 2(2*1+1)
for l = 2 means d subshell no. of electrons = 10 = 2(2*2+1)
similarly for others
