Question

Quizplus · Accepted Answer

Atomic radii tend to increase down a group because the number of energy levels or shells increases, leading to an increase in distance between the nucleus and the outermost electrons. Atomic radii tend to decrease across a period because the number of protons within the same energy level increases, resulting in a greater attractive force between the nucleus and the electrons in that energy level, making the atomic radius smaller.
