Question & Answer
Choose the Best Answer
Nonmetals have fewer electrons in their outer shell.
Nonmetals have a stronger effective nuclear charge that holds onto their electrons more tightly.
Metals readily lose electrons to achieve stability.
Nonmetals are larger in atomic size than metals.
Understanding the Answer
Let's break down why this is correct
Nonmetals have a higher effective nuclear charge, which is the net positive pull felt by the electrons after shielding by inner electrons. Other options are incorrect because The idea that fewer outer‑shell electrons make it hard to remove an electron is a misconception; Metals have low effective nuclear charge for their outer electrons, which is why they lose electrons easily.

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.
