1 point

Atomic Size

Electronegativity

Metallic Character

Density

​

Answer 1

Answer:

The reactivity of group 1 elements increases as you go down the group because: the atoms become larger. the outer electron becomes further from the nucleus. the force of attraction between the nucleus and the outer electron decreases.

Answer 2

Answer:

Both the melting and boiling points decrease down the group .

Explanation:

When any of the Group 1 metals is melted, the metallic bond is weakened enough for the atoms to move more freely, and is broken completely when the boiling point is reached.
