Subject: Inorganic Chemistry · Chapter: Periodic Properties · Topic: Periodic Properties – General · Exam: JAM 2005-2022 · Marks: 2 · Difficulty: Easy
With respect to periodic properties, the CORRECT statement is
(a)Electron affinity order is $\mathrm{F}>\mathrm{O}>\mathrm{Cl}$
(b)First ionisation energy order is $\mathrm{Al}>\mathrm{Mg}>\mathrm{K}$
(c)Atomic radius order is $\mathrm{N}>\mathrm{P}>$ As
(d)Ionic radius order is $\mathrm{K}^{+}>\mathrm{Ca}^{2+}>\mathrm{Mg}^{2+}$
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
K⁺ > Ca²⁺ > Mg²⁺ is the correct ionic-radius order; EA is Cl > F > O, IE₁ is Mg > Al > K, and radius is As > P > N (d).
