Two elements 1 and 2 are in the same row of the periodic table but not next to each other. Element 1 has a larger atomic radius than element 2, which of the following are most likely to be true about their relative ionization energies and why? O e a. I and IV b. II and IV c. III and VI d. I and V e. Il and V O b Od O a I. Element 1 has a larger ionization energy II. Element 2 has a larger ionization energy III. They both have the same ionization energy Because O c IV. electrons in element 1 are more strongly attracted to the nucleus V. electrons in element 2 are more strongly attracted to the nucleus VI. electrons are being removed from the same quantum shell
