In general, where in the periodic table of elements are the elements with the largest atomic radii located?

The elements with the largest atomic radii are typically found in the bottom-left corner of the periodic table. This is due to the fact that atomic radius increases as you move down a group in the table because additional electron shells are added, causing the outermost electrons to be farther from the nucleus. Additionally, within a period, the atomic radius tends to decrease as you move from left to right because the increase in positive charge in the nucleus pulls the electron cloud closer to the nucleus, reducing the size of the atom.

In the bottom-left corner, you will find the alkali metals, which have larger atomic radii compared to other elements. This combination of being low in the table and to the left captures the trend of larger atomic size effectively. Therefore, the option indicating the bottom-left corner accurately reflects where elements with the largest atomic radii are located on the periodic table.
