The atomic radius decrease, with several exceptions in periods 6 and 5.
The atomic radius tends to decrease from left to right across a period.
The atomic radius decreases.
Potassium has the largest atomic radius. It is in the 1st group of the periodic table. Fluorine has the least atomic radius.
Down a group, the atomic radius increases as the number of shells or energy levels increases.
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
Atomic Radius gets greater down the periodic table and gets smaller to the right in the periodic table. This means, in order of atomic radius, that the five smallest elements are Helium, Neon, Fluorine, Oxygen, and Hydrogen in that order.

Francium has the largest atomic radius of all the elements on the Periodic Table.

Francium. The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
Lithium(520)
The atomic radius decrease from left to right in the periodic table.
atomic radius decreases from bottom to top of the periodic table.
Atoms to the left on the periodic table Atoms with a large atomic radius
The elements with the smallest atomic radii are found in the top of the P block of the periodic table. Helium (He) has the smallest atomic radius. Francium, on the other side of the periodic table (very bottom of the S block), has the largest atomic radius.
