Question

3. Which of the following orbital designations are correct 1s, 1p, 7d, 9s, 3f, 4f, 2d 4. for the principal quantum 5 - a) what are the possible values of b) What are the possible m values c) How many total electrons in the primary shell

Answer 1

3 for varies is IP Td - gs - 3 f » 4 f = ad any principal quantum number (2), I from to nt. n=1 l=0 we know that I n=1, 1=0 (not possible) for s eso n=7, f = 0,1,2,3,4,5,6, P is a n=9, 120 11,2,34,5,6,7,8 is 2 n=3. 1 = 0, 1, 2 (not possible) n = 4, 1 = 0,1,2,3 n=2, 1=0,1 (not possible) to eo es 3.

so except IP, 3f and ad all are possible orbital designation are correct. for n=5. al varies from oto nol. i l= 0,1,2,3,4 (6 for given e me naries as 0, 21, 22. Il l=0 m=0 l=4 , m = -4,-3, -2,-1,0,17 l=1 , 314 m = -1,0,1 d=2 , m = -21-110,1,2 l=3 m = -3,-2,-1,0, 1,2,3,
4.(c) Primary shell is S, and electrons in this shell is 2.
