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)
What else can I help you with?
Whats the Largest metolloid on periodic table?
Astatine is the largest metalloid on the periodic table. This metalloid has an atomic number of 85. Its molar mass is 210 gram per mol.
Which atom has the largest atomic raidius?
Francium has the largest atomic radius among all elements.
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.
Which element has the largest radius?
francium has the largest ionic radius
Is francium the largest and most reactive metal?
Francium is the largest alkali metal, but it is not the largest or most reactive metal overall. It is highly reactive due to its position on the periodic table, which means it will react violently with water and air. However, there are other metals that are more reactive than francium, such as cesium and potassium.

Which element has the smallest atomic radius rubidium cesium and francium?
Francium has the largest atomic radius among rubidium, cesium, and francium, as atomic radius generally increases down a group in the periodic table.
