The valence electrons of an atom are at the lowest energy level because their increased distance from the nucleus reduces their attraction to the atom's protons.

Question

Quizplus · Accepted Answer

Valence electrons are located in the outermost energy level of an atom, which is also known as the valence shell. This energy level is not necessarily the lowest energy level, but it is the highest energy level that contains electrons. The valence electrons are attracted to the nucleus by the positive charge of the protons, but their distance from the nucleus and the shielding effect of inner electrons can reduce this attraction.
