Answer to Question #268646 in General Chemistry for MCC

Question

Identify if the given set is a valid set of quantum numbers? Explain your answer.

a. n = 2,  l = 2,  ml = 0, and  ms = -1/2  

b. n = 2,  l = 1,  ml = -1, and ms = -1/2

c. n = 3,  l = 0,  ml = 0, and ms = 1    

d. n = 3,  l = 2,  ml = 3, and ms = 1/2 

Answer 1

Option A and C are not correct.

Option A is not correct because its not possible for principal quantum number and azimuthal quantum number to be of same value.The principal quantum number value must always be bigger.

Option B is not correct because spin quantum number can only have two values which are (1/2) or (-1/2) so it's not possible to have a value such as 1 .
