looking for some guidance? lets work through a few related
practice questions before you go back to the real thing.
this wont impact your score, so stop at anytime and ask for
clarification whenever you need it.

Explanation:

In the quantum - mechanical model:

• Electron paths cannot be described exactly due to the Heisenberg uncertainty principle.
• Electrons exhibit both particle - like (e.g., in the photoelectric effect) and wave - like (e.g., electron diffraction) behavior.
• Orbitals are not specific paths. They are probability maps (regions where electrons are likely to be found).

Answer:

Electrons do not behave as particles; Orbitals are specific paths electrons follow; All of the above are correct statements.
