Electron affinity of halogens (A) F > I > Br > Cl (B) Cl > Br > F > I (C) Cl > F > Br > I (D) I > Br > Cl > F A B C D 4 / 15 4. The IUPAC name of the Super Heavy Element having atomic number 122 is (A) Unbiibium (B) Unbibium (C) Undidium (D) Undidiium A B C D Answer: UnbibiumExplanation: IUPAC temporary naming uses roots: 1 = un, 2 = bi → 122 = un-bi-bi-um. 5 / 15 5. Find out the correct order of ionic radii (A) Na⁺ > Al³⁺ > Mg²⁺ > Si⁴⁺(B) Si⁴⁺ > Al³⁺ > Mg²⁺ > Na⁺(C) Na⁺ > Mg²⁺ > Al³⁺ > Si⁴⁺(D) Mg²⁺ > Al³⁺ > Si⁴⁺ > Na⁺ A B C D Explanation: Same electrons, higher charge → smaller radius. 6 / 15 6. First Ionization Energy order (A) Be > B > C > N(B) Be > B < C < N(C) B > Be > N > C(D) N > B > C > Be A B C D Explanation: General increase across period with anomaly. 7 / 15 7. Find out the correct order of ionic radii (A) N³⁻ > O²⁻ > Na⁺ > Mg²⁺(B) O²⁻ > N³⁻ > Na⁺ > Mg²⁺(C) Mg²⁺ > Na⁺ > O²⁻ > N³⁻(D) Na⁺ > N³⁻ > Mg²⁺ > O²⁻ A B C D Explanation: More negative ions are larger. 8 / 15 8. Which one is correct statement regarding the various types of radii? (A) Atomic radii > cationic radii (B) Van der Waals radii < atomic radii (C) Cationic radii > Van der Waals radii (D) Anionic radii < cationic radii A B C D Explanation: Cations are smaller; Van der Waals radius is largest. 9 / 15 9. Electronegativity order (A) B > Al > Ga > In(B) In > Ga > Al > B(C) Al > B > Ga > In(D) B > Al < Ga > In A B C D Explanation: EN decreases down group. 10 / 15 10. Which species is most known? (A) AsCl₅ (B) NCl₅ (C) PCl₅ (D) PCl₆⁻ A B C D Explanation: PCl₅ stable due to expanded octet. 11 / 15 11. Electron affinity order (A) Be > B > C > N (B) Be > B < C < N (C) Be < B < C > N (D) N > O > C > B A B C D Explanation: N shows exception (half-filled stability). 12 / 15 12. Electron affinity order (A) F > Cl > Br > I (B) O > S > Se > Te (C) P > N > As > Sb (D) He < Ne < Ar < Kr A B C D Explanation: EA decreases down group. BUT Cl>F & S>O 13 / 15 13. Correct order of Electron Affinity (A) N > O (B) He < Ne (C) P > N (D) Be > B A B C D Explanation: N has lower EA than P. 14 / 15 14. Which is non-existing?
