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
Potassium has the largest atomic radius. It is in the 1st group of the periodic table. Fluorine has the least atomic radius.
Atomic radius increases down the group. So indium will have the largest atomic radius among the options given.
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.

Chlorine will have the smallest atomic radius, bromine the largest.
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.
Noble gases have the smallest atomic radius.
It is helium that has the smallest atomic radius. Use the link below to see a list of elements arranged by atomic radius.
N, P, As and Sb
N, P, As and Sb
Group-1 has largest atomic radius. It decreases across a period
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.
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.
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
