Which element will have a larger atomic radius magnesium or cesium?

Cesium will have a larger atomic radius than magnesium. This is because atomic radius tends to increase down a group in the periodic table, and cesium is located below magnesium in the periodic table.


Which has the greatest atomic radius Pb or Ge?

Lead (Pb) has a greater atomic radius than germanium (Ge) because atomic radius generally increases down a group in the periodic table. Lead is located below germanium in the periodic table, so it has more electron shells and a larger atomic radius.

Which has the larger atomic radius silicon or bromine?

Silicon has a larger atomic radius than bromine. This is because as you move down a group on the periodic table, atomic radius tends to increase. Bromine is located further to the right on the periodic table and has a smaller atomic radius compared to silicon.
