Answer:
The magnetic quantum number (l) determines the orientation of an orbital
Explanation:
The magnetic quantum number of an electron's orbital is the spatial orientation of the electron's orbital
The magnetic quantum number, ml, specifies the orientation and number of orbitals of electrons in a subshell. The value of the magnetic quantum number is dependent on the angular momentum quantum number I with values ranging from -I to +I.
The shape of the electron's orbital is determined by the angular momentum quantum number.
