Question & Answer
Choose the Best Answer
The shielding effect increases nuclear attraction, reducing reactivity.
The shielding effect decreases the effective nuclear charge felt by the valence electrons, increasing reactivity.
The shielding effect has no impact on reactivity or bonding.
The shielding effect causes an increase in ionization energy, thereby decreasing reactivity.
Understanding the Answer
Let's break down why this is correct
Shielding reduces the pull felt by the outer electron, which is called the effective nuclear charge. Other options are incorrect because The idea that shielding makes the nucleus pull harder is a misunderstanding; Ignoring shielding ignores how electrons block the pull of the nucleus.

Definition
Periodic properties describe the trends in atomic size, ionization potential, electron affinity, electronegativity, metallic character, and non-metallic character across periods and groups. These properties help in understanding the reactivity and behavior of elements within the Periodic Table.
