Question

Match the quantum numbers to what it signifies.

• A. Energy of orbitals
• B. Shape of orbitals
• C. Orientation of orbitals

Answer 1

The principal quantum number $\left(n\right)$ determines the overall size and energy of an orbital. Its possible values are $n=1,2,3$...

Azimuthal quantum number $\left(l\right)$ determines the shape of an orbital. Its possible values are $l=0,1,2,3...(n-1)$.

Magnetic quantum number $\left(m_l\right)$ determines the orientation of an orbital. Its possible values are $m_l=-l,...-1,0,1,...l$.
