The shape of orbitals are related to the ratio of principal quantum number (n) to substiary quantum number (k,a modifacation of Bohr-sommerfield theory ).The value of k for any shell has a value ranging betwe3en n to l .The amximum value for k is given for x sub-shell white k becomes with p, d,f........ repectively upto minimum value

If n is the major axis and k is th e minor axis , then `n//k = 1` for circular shape white `n//k gt 1` for elliptical shape
Which is correct according to the increasing elliptical number of sub-shell ?

Options

C. `4d lt2s lt 3plt 5p`
D. `3p lt4d lt 2slt 5d`

Answer

A
