Respuesta :

Answer: Bothe reactivity and electronegativity decrease down a group

Explanation:

pstnonsonjoku

Electronegativity decreases down a group, and reactivity increases down a group.

Metals are electropositive. They loose electrons when they react. The ability to loose electrons increases down the group as more shells are added and the outermost electrons lie at a greater distance from the nucleus.

As this ability to loose electrons increases down the group, electronegativity decreases down the group just as reactivity increases down the group.
