Question

current attempt in progress which one of the following terms describes the shape of an orbital? the principal quantum number the magnetic quantum number the azimuthal quantum number the spin orientation quantum number none of the above

Explanation:

The principal quantum number ($n$) describes the energy level and size of the orbital. The magnetic quantum number ($m_l$) describes the orientation of the orbital in space. The azimuthal quantum number ($l$) determines the shape of the orbital (e.g., $l = 0$ is s - orbital which is spherical, $l=1$ is p - orbital which is dumb - bell shaped). The spin - orientation quantum number ($m_s$) describes the spin of the electron.

Answer:

The azimuthal quantum number
