Elements, like francium, located at the bottom of a group have a lower

attraction for their valence electrons because they have a

O

A. small atomic radius.

B. high electronegativity.

O

O

C. large atomic radius.

O

D. high ionization energy.

The interaction between the nucleus of the atom and its electrons is due to the electric force between them, which decreases with the square of the distance, according to the coulomb's law. The valence electrons are located in the farthest orbit of the nucleus, the greater the atomic radius the greater this distance between the nucleus and valence electrons, which causes the attraction force decreases.
