Which of the following statements is TRUE? A) The principal quantum number (n) describes the shape of an orbital. B) The angular momentum quantum number (l) describes the 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_l) corresponds to the orientation of an orbital, while the principal quantum number (n) corresponds to the energy level of an orbital and the angular momentum quantum number (l) corresponds to the shape of an orbital. Choice A is incorrect, as it incorrectly describes the role of the principal quantum number. Choice B is also incorrect, as it describes two separate qualities (size and energy) associated with an orbital, rather than just one quantum number. Choice D is incorrect, as it describes the outdated Bohr model of the atom, in which electrons were thought to follow specific paths around the nucleus.
