Janessa Case · Answer 1

The correct answer is 2.

2 is correct because the number of charges on the nucleus increases, causing a stronger attraction for the bonding of electrons (and thus greater electronegativity).

1 is incorrect because the atomic radius decreases.

3 is incorrect because the atomic mass increases.
