Electrons surround the nucleus of an atom, and those that are in the outer energy levels are:

A. less attracted to the nucleus

B. more attracted to the nucleus

C. not able to conduct a current

D. unavailable to interact with other chemicals

Asked by historygeek96

Answer (2)

More attracted to the nucleus because they are further from the nucleus. In addition, the screening effect, repulsion of inner electrons on the valence electrons, will effectively reduce the attraction of the valence electrons toward the nucleus.

Electrons in the outer energy levels of an atom are less attracted to the nucleus due to being further away and experiencing the shielding effect from inner electrons. Therefore, they are not as strongly held compared to electrons closer to the nucleus. The correct answer is A. less attracted to the nucleus.
