Web10 de ago. de 2024 · The atomic radius of an element is half of the distance between the centers of two atoms of that element that are just touching each other. Generally, the atomic radius decreases across a period from left to right and increases down a given group. The atoms with the largest atomic radii are located in Group I and at the bottom of groups. An atom is a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.
