Which of the following sets of quantum numbers are followed ?

Options

A. n = 1,l = 0 and m = 0
B. n = 2, l = 1 and m = + 1
C. n = 1, l = 0 and m = + 1
D. n = 2,l = 2 and m = 0

Answer

A, B

Explanation

c. and .d. option are not correct because :
.m. cannot be `pm 1 ` for l = 0 and .l. cannot be equal to .2. for n = 2
value of m = -1 _____ 0 _____ + 1
Values of l=0 ,1,2, ….. (n-1)
