Answer A: B r has a lower electronegativity than I does.
A

Br has a lower ionization energy than I does.

Answer B: B r has a lower ionization energy than I does.
B

An added electron would go into a new shell in Br but not in I.

Answer C: An added electron would go into a new shell in B r but not in I .
C

There is a greater attraction between an added electron and the nucleus in Br than in I.
