Yes
atomic radius decreases from bottom to top of the periodic table.
It tends to increaseThe atomic radius increases down the group
The atomic radius increases from top to bottom within a group.
In the group 2 (IUPAC name) of the periodic table the atomic radius increase from beryllium to radium.
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
atomic radius decreases from bottom to top of the periodic table.
The group trend for atomic radius is that it tends to increase down a group in the periodic table. This is because as you move down a group, the number of electron shells increases, leading to a larger atomic radius. Additionally, the effective nuclear charge decreases down a group, which also contributes to the increase in atomic radius.
Atomic size increases down a group as the energy level (or shell) increases. So Astatine will have the largest size (radius) in group 17

Fr (Francium) has a larger atomic radius than F (Fluorine) because atomic radius increases as you move down a group in the periodic table. Francium is located at the bottom of the alkali metal group while Fluorine is at the top of the halogen group.
Atomic Mass
The element in group 3A with the largest atomic radius is thallium (Tl). As you move down a group on the periodic table, the atomic radius tends to increase due to the addition of more electron shells. Thallium, being lower in the group, will have a larger atomic radius compared to other elements in group 3A.
Bromine has the largest atomic radius among fluorine, chlorine, and bromine. Atomic radius increases down a group on the periodic table, so bromine, located at the bottom, has the largest atomic radius of the three elements.
Atomic size generally increases from top to bottom within a group on the periodic table. This is because each successive element has an additional energy level of electrons, leading to increased electron-electron repulsion and an overall increase in atomic size.
