Many energy levels of electrons and low effective nuclear charge/low Coulombic force.
Fr
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.
Group-1 has largest atomic radius. It decreases across a period
NA
Fr
Atomic radius increases going down the periodic table and going from right to left, meaning that Fr (Francium) has the largest atomic radius and He (Helium) has the smallest. Therefore, Cl<S<P<Si<Al So the answer is Cl
Potassium has the largest atomic radius. It is in the 1st group of the periodic table. Fluorine has the least atomic radius.
Chlorine will have the smallest atomic radius, bromine the largest.
Francium has the largest atomic radius in Group 1 of the Periodic Table.
Atomic radius increases down the group. So indium will have the largest atomic radius among the options given.
Argon doesnt have the smallest atomic radius, its chlorine.Argon has the largest atomic radius in period 3.
Francium has the largest atomic radius of all the elements on the Periodic Table.
Group-1 has largest atomic radius. It decreases across a period
Atomic radius increases down the group. So larger atomic radius are present at the bottom.
Potassium has the largest atomic radius.
NA
