Question

which of the following statements about the quantum - mechanical model is false?
electron paths cannot be described exactly.
electrons do not behave as particles.
orbitals are specific paths electrons follow.
orbitals are a probability map of finding electrons.
all of the above are correct statements.

Explanation:

• In the quantum - mechanical model, electrons have both particle - like and wave - like properties (wave - particle duality). So the statement "Electrons do not behave as particles" is false.
• Electron paths cannot be described exactly (due to the Heisenberg uncertainty principle), and orbitals are a probability map of finding electrons (not specific paths).

Answer:

Electrons do not behave as particles.
