Question

10.   The first ionization energy for aluminum (Al) is 578 kJ while that for magnesium (Mg) is 738 kJ. This tells us that:

a)      more energy is required to remove an electron from Mg than for Al

b)      more energy is released in removing an electron from Mg than for Al

c)      more energy is required when Mg accepts an electron than for Al

d)      not possible to answer unless the electron affinity is known

e)      more energy is released when Mg accepts an electron than for Al

please explain why i am very confused with the why behind this question. I know that ionization energy is energy required to remove an electron I just don't know how to apply to this question
