Question & Answer
Choose the Best Answer
Ionization potential decreases due to increased electron shielding in subshells.
Ionization potential increases as subshells fill, causing stronger attraction to the nucleus.
Ionization potential remains constant across the period as electron affinity does not change.
Ionization potential decreases because elements with high electron affinity have lower ionization energy.
Understanding the Answer
Let's break down why this is correct
As we move across period 2, the number of protons in the nucleus rises. Other options are incorrect because The idea that shielding increases enough to lower ionization energy is wrong; Ionization energy does change across the period.

Definition
Ionization potential is the energy required to remove an electron from an atom's outermost shell. It varies across periods and groups in the Periodic Table, influencing the element's reactivity and ability to form ions. Understanding ionization potential helps in predicting chemical behavior and bonding patterns.
