Question

Which quantum number defines the orientation of orbital in the space around the nucleus?

• A. Principal quantum number $\left(n\right)$
• B. Azimuthal quantum number $\left(l\right)$
• C. Magnetic quantum number $\left(m_l\right)$
• D. Spin quantum number $\left(m_s\right)$

Answer 1

The correct option is C Magnetic quantum number $\left(m_l\right)$

Magnetic quantum number$\left(m_l\right)$ represents orientation of an orbital with respect to the coordinate axes.
