Question

question 3 (2 points)
the angular momentum quantum number (l) describes ______________.
○ the spin of the electron
○ the 3 - d orientation of the orbital
○ the shape of the orbital
○ the distance from the nucleus

Explanation:

The angular - momentum quantum number (l) in quantum mechanics determines the shape of the atomic orbital. The spin of the electron is described by the spin quantum number (ms), the 3 - D orientation of the orbital is described by the magnetic quantum number (ml), and the distance from the nucleus is related to the principal quantum number (n).

Answer:

the shape of the orbital
