What value of l is represented by a d orbital? A) 1 B) 2 C) 0 D) 3

Answer: B) 2

Explanation: In quantum mechanics, the value of \( l \) (the azimuthal quantum number) determines the shape of the orbital. For d orbitals, \( l \) is equal to 2. The values of \( l \) correspond to different types of orbitals: \( l = 0 \) for s orbitals, \( l = 1 \) for p orbitals, \( l = 2 \) for d orbitals, and \( l = 3 \) for f orbitals.
