Answer 1

The correct option that describes the pattern of electronegativity and reactivity in metals is:

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

As you move down a group in the periodic table, electronegativity tends to decrease because the atoms become larger and the attraction between the nucleus and the valence electrons decreases. In contrast, the reactivity of metals generally increases as you move down a group due to the decrease in ionization energy, making it easier for metals to lose electrons and react.
