The element expected to form largest ion to achieve the nearest noble gas configuration is (A) F (B) — NEET Chemistry Past Papers Chemistry Question

💡 Solution & Explanation

F–1, N–3, Na+ & O–2 all ions are isoelectronic containing 10 e– Zeff → Na+ > F– > O–2 > N–3 order of radius → N–3 > O–2 > F– > Na+ → Nitrogen to achieve Noble gas configuration it gain 3 e– , & form N–3
