2p orbitals have n = 1,l = 2 n=1, l = 0 n = 2, l = 0 n = 2, l =1 :

Using the s,p,d notations, describe the orbital with the following quantum numbers : (a) n = 1, l = 0 " " (b) n = 3, l = 2 (c ) n = 3, l = 1 " " (d) n = 2, l = 1 (e ) n = 4, l = 3 " " (f) n = 4, l = 2 .

Describe the orbital with the following quantum numbers : (i) n = 1, l = 0 " " (ii) n = 2, l = 1, m = 0 (iii) n = 3, l = 2 " " (iv) n = 4, l = 1 (v) n = 3, l = 0, m = 0 " " (vi) n = 3, l = 1 .

.What designations are given to the orbitals having (i) n = 2, l = 1 (ii) n = 2, l = 0 (iii) n = 4, l = 3 (iv) n = 4, l = 2 (v) n = 4, l = 1?

Explain giving reasons, which of the following sets of quantum numbers are not possible. a) n = 0, l = 0 m_l =0 , m_s = + 1//2 b) n = 1, l = 0, m_l = 0 , m_s = +1//2 c) n = 1, l = 1 m_l = 0 , m_s = + 1//2 d) n = 2, l = 3 m_l = 0 , m_s = -1//2 e) n = 3, l=3 m_l = -3, m_s = + 1//2 f) n = 3, l = 1 m_l = 0 , m_s = + 1//2

How many electron states are in these subshells: (a) n=4,l=3 , (b) n=3,l=2, (c ) n=4,l=1, (d) n=2,l=0 ?

Using the s,p, d notation , deseribe the orbit with the following number a n = 1, l = 0 b. n = 2, l = 0 c. n = 3, l = 3 d. n = 4, l = 2 e. n = 4, l = 3

Give the designation of orbital when ltbr. (i) n=2, l=0 " " (ii) n=3, l=2 (iii) n=5, l=1 " " (iv) n=4, l=3.
