Question

According to the quantum mechanical model, where are electrons located?

Select one:
A. in orbits around the nucleus
B inside the nucleus
C. at great distances from the nucleus
D. in the cloud-like areas around the nucleus

Answer 1

D.) in the cloud-like areas around the nucleus

Step-by-step explanation:

A.) is incorrect. Electrons exist in orbitals in the Bohr's Model.

B.) is incorrect. Electrons do not exist in the nucleus. They always exist outside of the nucleus, but their exact position has been debated.

C.) is incorrect. While the electron clouds in the quantum mechanical model can cover a relatively large amount of space, the distance from the nucleus is not great. Within this cloud, electrons can exist closer to the nucleus at a particular time.

D.) is correct. Electrons are said to exist somewhere within these clouds around the nucleus. The model uses the cloud references to display how you can never be sure where the electrons are located - they are always moving around.
