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

Answer 1

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

Reason: Atomic size and shielding increase down a group, lowering electronegativity and ionization energy, so metals more readily lose electrons (become more reactive).
