Which option correctly describes the pattern of electronegativity and reactivity in metals?(1 point)

Question

Electronegativity increases down a group, and reactivity decreases down a group.
Both electronegativity and reactivity decrease down a group.
Electronegativity decreases down a group, and reactivity increases down a group.
Both electronegativity and reactivity increase down a group.

Answer 1

The correct option is: Electronegativity decreases down a group, and reactivity increases down a group.

In general, for metals, electronegativity tends to decrease as you move down a group in the periodic table, while their reactivity tends to increase. This is because as you go down a group, the outermost electrons are further from the nucleus and are more easily lost, making the metals more reactive.
