    Fr (Francium) has a larger atomic radius than F (Fluorine).

    Atomic radius refers to the size of an atom, which is determined by the distance between the nucleus and the outermost electrons. Francium (Fr) is a metal element located in the bottom row of the periodic table, also known as the alkali metals group. The alkali metals have one valence electron that is located in the outermost shell, and as we move down the group, the number of shells increases. This results in a larger atomic radius for elements towards the bottom of the group. Francium, being the largest element in the group, has the largest atomic radius.

    Fluorine (F), on the other hand, is a non-metal element located in the top right corner of the periodic table. Non-metals have a higher electronegativity and tend to attract electrons towards themselves, resulting in a smaller atomic radius. Fluorine, being the smallest element in the halogens group, has the smallest atomic radius.

    Therefore, Fr has a larger atomic radius than F.
