Lonization energy shows specific trends when moving left to right across a period and when moving top to bottom down a group. Which statement identifies the Group 17 element with the HIGHEST ionization energy and explains why? A:lodine
It has the greatest atomic mass, meaning the gravitational attraction between the nucleus and electrons is the greatest; therefore, it would require the most energy to remove a valence electron. B:Fluorine
It has the smallest atomic radius within the group and would experience the least amount of attraction between of the nucleus and inner electrons; therefore, it would require the greatest amou of energy to remove a valence electron
C:Fluorine
Its valence electrons experience the greatest amount of attractive force from the
nucleus because it has the fewest number of energy levels; therefore, it would
require the greatest amount of energy to remove an electron.
D:lodine
It has a higher atomic number, which means its nuclear charge is higher, making
the attractive force greatest between the nudimeus and valence electrons;
therefore, it would require the most energy to remove an electron.
