Which Group 17 Element Has the Least Attraction for Electrons?

All halogens have seven valence electrons, but as the atomic size increases, the attraction between the nucleus and these outer electrons decreases. The largest halogen atom is astatine

astatine
Astatine is a chemical element with the symbol At and atomic number 85. Many of them have been estimated based on the element's position on the periodic table as a heavier analog of iodine, and a member of the halogens (the group of elements including fluorine, chlorine, bromine, and iodine). ...

. Therefore, astatine has the least attraction for electrons of all the halogens.

Which group 17 element has the weakest attraction for electrons?

Halogens are nonmetals in group 17 (or VII) of the periodic table. Down the group, atom size increases. As a diatomic molecule, fluorine has the weakest bond due to repulsion between electrons of the small atoms. Due to increased strength of Van der Waals forces down the group, the boiling points of halogens increase.

What element has the least attraction for electrons?

Electrons closer to the center are held more tightly as proton number increases. However, outermost electrons are held less tightly because inner electrons shield them. For this reason, it is astatine that has the least attraction for its outer electrons.
