In general, atomic size decreases across a period - however making ions changes this general trend. All of the above ions would have the same number of electrons, so one needs to consider the number of protons in the ion. Polonium has the fewest protons, so it cannot pull as strongly on the same number of electrons as Radium - for this reason, Po2- would be the largest, then At1-, then Fr1+, and lastly Ra2+ would be the smallest.
(All the above elements are somewhat rare, so calculating the exact size of each ion would be difficult with high precision - however based on periodic trends one can make a good estimate)

Which element has the largest size of atoms?
Atomic radii have not been measured or calculated based on theoretical principles for all of the elements. However, based on the information available in the wikipedia tables of atomic radii it would appear that the largest atom will prove to be that of francium.
The most active metal would be the one that is?
largest
What is the largest natural element?
Bismuth Francium has the largest atom - the greatest atomic radius.
Which atom has the largest atomic raidius?
This chemical element is francium.
Is francium the largest and most reactive metal?
Francium (Fr) should, based on its position in the periodic table, be the most reactive metallic element. However, fluorine is the most reactive element generally.
Does Francium have the largest atomic radius on the periodic table?
Francium has the largest atomic radius in Group 1 of the Periodic Table.
