Question

which electron position experiences the weakest attraction from the nucleus?
the first energy level.
the second energy level.
the electrons all experience the same attractive force, regardless of the energy level.
the fourth energy level.

Explanation:

Electrostatic attraction between the nucleus and electrons decreases with increasing distance from the nucleus. Higher energy levels are farther from the nucleus, so electrons in them experience weaker attraction. The fourth energy level is the outermost/farthest here.

Answer:

The fourth energy level.
