Concept: Magnetic Quantum Number

# Problem: What are the possible values of n and ml for an electron in a 5d orbital ? A) n = 5 and ml = -2, -1, 0, +1, or +2 B) n = 1, 2, 3, 4, or 5 and ml = 2 C) n = 5 and ml = 2 D) n = 1, 2, 3, 4, or 5 and ml = -2, -1, 0, +1, or +2

###### FREE Expert Solution

To solve this problem, let’s first define the values of the first three quantum numbers:

• principal quantum number (n) energy level in orbitals and its value could be any positive integerstarting from 1 to infinity
• angular momentum quantum number (→ (l) has to be at least 1 less than n,range of values from 0 up to (n-1)
• magnetic quantum number (m)→ range of values from - to +.
