Q7.04 Homework Answered Which of the following combinations of n and I are not allowed? O A n=1 and l=0 o B n =3 and l = 1 C n=4 and l = 0 o D n=2 and l = 2 O E n=5 and l = 3

Answer 1

n. Q.7.04: We know - n = principle quantum no. 1 = Azimuthal quantum no. And, Avale lol11213 orbital s þ 10 vind the no. of orbital is dependent on Now - A. = 1 and 1=0 :: 1 =0 means orbital in 's'. · Designation will be — 15. it's possible. B. n=3 and d = 1 i 1 = 1 means orbital is p. i Designation 3p it's also possible.

n = 4 and 1=0. :: 1=0 means orbital in 's'. in Designation - AS it's possible. 8=2 and 1=2 . 1=2 means orbital is d'. .: Designation -> 2d it's not possible cause no. of orbital depends on principle quam tum no.(n). Hene, n=2. i.e. no. of on bital will be 2. Which will be s and e. So, it's not possible to be '2d. E. D=5 and 1 = 3 4= 3 means orbital ist! Designation → 54 . it's possible.
