Question

If the quantum number l has a value of 2, what are the permitted values of the quantum number m?

• A. -2, -1, 0, 1, 2
• B. 0,1,2,3,4
• C. 0,1,2
• D. -1,0,1

Answer 1

The correct option is A -2, -1, 0, 1, 2

As we know,
value of l = o to n-1
and
value of m = -l to +l
so for l=2
m = -2,-1,0,+1,+2
