Periodic table introduction quick check. Where do you find the atoms with the largest atomic radius on the periodic table?

Answer 1

Atoms with the largest atomic radius are typically found in the lower-left corner of the periodic table. This is because atomic radius increases down a group (as additional electron shells are added) and decreases across a period from left to right (due to increasing nuclear charge, which pulls electrons closer to the nucleus). Therefore, elements in Group 1 (alkali metals) and towards the bottom of the table, like cesium (Cs) or francium (Fr), have the largest atomic radii.
