Which of the following best helps to explain why the electron affinity of Br has a greater magnitude than that of I?
A) Br has a lower electronegativity than I does.
B) Br has a lower ionization energy than I does.
C)An added electron would go into a new shell in Br but not in I
(D) There is a greater attraction between an added electron and the nucleus in Br than in I.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
