The atomic radius decrease, with several exceptions in periods 6 and 5.
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.
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.

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.
The atomic radius of gallium is about 135 picometers. In the periodic table, gallium has a larger atomic radius compared to elements to its left and a smaller atomic radius compared to elements to its right.
The atomic radius decreases.
The atomic radius of manganese is about 127 picometers. In the periodic table, manganese has a smaller atomic radius compared to elements in the same period but larger than elements in the same group.
Francium has the largest atomic radius of all the elements on the Periodic Table.
Potassium has the largest atomic radius. It is in the 1st group of the periodic table. Fluorine has the least atomic radius.

The atomic radius of helium is about 31 picometers. Helium has one of the smallest atomic radii among all the elements in the periodic table due to its small size and high nuclear charge.
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.
Francium. The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
atomic radius decreases from bottom to top of the periodic table.
