Answer 1

sadium elements have the highest atomic radii

Answer 2

Answer:

franicium

Explanation:

Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
