Answer:
Ca is more reactive because it has a lower
ionization energy than Mg. This is because it is lower in the periodic table. The added central electrons added over the extra period provide shielding in the center of the atom
Bromine 35
Chlorine 17
Flourine 9
Iodine 53
Astatine 85
Answer: none of the above
