Front

Which conclusion cannot be drawn from the graph showing ionization energy values on the periodic table? Options: The ionization energy drops significantly as you move down a group because the valence electrons are in a shell further from the nucleus., The ionization energy increases gradually as you move right across a period because the valence electrons are in a shell further from the nucleus., The ionization energy increases gradually as you move right across a period because you are adding more protons., The ionization energy increases when the valence electrons are more attracted to the nucleus.

Back

The ionization energy increases gradually as you move right across a period because the valence electrons are in a shell further from the nucleus.
