Question & Answer
Choose the Best Answer
Increased nuclear charge pulls electrons closer to the nucleus
Electrons are added to the outer shell, increasing size
Shielding effect increases, causing a larger radius
Electrons are lost during bonding, leading to a smaller radius
Understanding the Answer
Let's break down why this is correct
When a new element is added to the same energy level, its nucleus gains another proton. Other options are incorrect because Adding electrons to the outer shell does not mean the atom grows; Shielding comes from inner electrons.

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.
