Which of the following statements are true? A)The principal quantum number (n)describes the shape of an orbital. B)The angular momentum quantum number (l)describes the size and energy associated with an orbital. C)The magnetic quantum number (m_l)describes the orientation of the orbital. D)An orbital is the path that an electron follows during its movement in an atom. E)All of the above are true.

Question

Quizplus · Accepted Answer

The magnetic quantum number (m) describes the orientation of the orbital, while the principal quantum number (n) describes the energy level and the angular momentum quantum number (l) describes the shape of the orbital. Choice D is incorrect as an orbital is actually a region of space where an electron is likely to be found, not a path that an electron follows. Therefore, only statement C is true.
