III. WHATI HAVE LEARNED. VALUATION/POST TEST:
Give the correct answers to the questions given below.

1. Which of the following sets of quantum numbers is/are possible? If the combination is not possible, explain why not,
a. n=4,1=2, m=0 c. n-5, 1-3, m=-3
b. n=3, 1=3, m=+1 d.n=3, I=0, m=+1 1

2. For each set of quantum numbers , state which one is invalid and why.
a.n= 1, 1= 1, m=0, m= +1/2 c. n= 3, = 1, m=2, m=-1/2 b. n= 2, 1= 1, m=-1, m,= +3/2 d. n=0, I= 0, m= 0, m,- +1/2

3. Refer to those sets of quantum numbers to answer the questions below.
I. n= 2, 1= 1, me 0, m= -1/2
II. n=4, = 4, mi = -2, m= +1/2
III. n= 3, 1, mi = 0, m=+1/2
iv. n= 1, 1=0, mı = 0, m= -1/2

a. Which set(s) is/are NOT allowable? Justify your answer.

b. Can the mi in set d have a value of -1? Explain.

c. Which set has I describing six electrons per orbital? Justify your answer

d. Which set(s) describe(s) an electron with a clockwise spin?

e. Which set has the greatest number of possible m values? Justify your answer.

II. Answer the following completely.

1. List all the possible combinations of the quantum numbers n. I, and ml if n= 4.

2. Give the complete set of quantum numbers of the last electrons of Gas31 and Sr38


PLEASE I NEED IT huhh . u can answer it atleast one but much better if u will answer it all. Thank youuuuuu​
