Question

Which of the following quantum numbers is not derived from the Schrodinger wave equation?

• A. Principal Quantum Number
• B. Azimuthal Quantum Number
• C. Magnetic Quantum Number
• D. Spin Quantum Number

Answer 1

The correct option is D Spin Quantum Number

Principal Quantum Number$\left(n\right)$, Azimuthal Quantum Number $\left(l\right)$ and Magnetic Quantum Number $\left(m_l\right)$ are derived from Schrodinger wave equation.
Spin quantum number is a quantum state that originates due to spinning of electrons about its own axis. It is not obtained from the Schrodinger wave equation.
