Periodic Trends in Group 15 Elements

Very Hard General Chemistry Atomic Structure And Periodic Trends

Consider the elements in the same group of the periodic table. Each element has a unique atomic structure leading to distinct chemical properties. One important factor influencing these properties is the effective nuclear charge (Z_eff), which affects the ionization energy and atomic radius as we move down a group. Which of the following statements accurately describes the relationship between atomic structure and periodic trends for the elements in Group 15 (Nitrogen Group) of the periodic table?

As you move down Group 15, the ionization energy increases due to increased nuclear charge.

As you move down Group 15, the atomic radius decreases due to increased electron shielding.

As you move down Group 15, the effective nuclear charge experienced by the valence electrons increases.

As you move down Group 15, the electronegativity generally decreases due to increased atomic size.
