Question & Answer
Choose the Best Answer
The metallic character decreases due to increased ionization energy.
The metallic character increases due to increased nuclear charge without increased shielding.
The metallic character increases due to increased shielding which allows outer electrons to be lost more easily.
The metallic character remains constant regardless of shielding effects.
Understanding the Answer
Let's break down why this is correct
Shielding happens when inner electrons block the pull of the nucleus on the outer electron. Other options are incorrect because The belief that metallicity falls because ionization energy rises is wrong; Thinking that metallicity rises solely because nuclear charge rises ignores shielding.

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.
