Flourine and Phosphorous.
Francium. The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
Group-1 has largest atomic radius. It decreases across a period
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.

Potassium has the largest atomic radius. It is in the 1st group of the periodic table. Fluorine has the least atomic radius.
Fluorine has the smallest atomic radius of all the p-block elements. This is because as you move across a period from left to right, the atomic radius decreases due to increasing nuclear charge pulling the electrons closer to the nucleus.
francium has the largest ionic radius
Among bromine, sulfur, chlorine, and selenium, chlorine has the smallest atomic radius. This is because atomic radius decreases as you move from left to right across a period on the periodic table. Chlorine is located on the right side of the periodic table in the 17th group, which indicates smaller atomic radius.
N (smallest radius) P As Sb (largest radius)
Francium. The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
Argon doesnt have the smallest atomic radius, its chlorine.Argon has the largest atomic radius in period 3.
It is helium that has the smallest atomic radius. Use the link below to see a list of elements arranged by atomic radius.
Fluorine has the smallest atomic radius among fluorine, oxygen, and chlorine. Oxygen has a larger atomic radius than fluorine but smaller than chlorine. Chlorine has the largest atomic radius among the three elements.

Lithium has the smallest atomic radius among the elements listed.
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius The protium isotope of hydrogen has the smallest nucleus radius. It is 1.6 fm
Francium has the largest atomic radius of all the elements on the Periodic Table.
