Periodic Table and Periodicity question

2022 · 27 Jun · Shift 1 · Q4

JEE MainChemistryPeriodic Table and PeriodicityMCQ+4 / −1
Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : The ionic radii of O2−O^{2-}O2− and Mg2+Mg^{2+}Mg2+ are same. Reason (R) : Both O2−O^{2-}O2− and Mg2+Mg^{2+}Mg2+ are isoelectronic species. In the light of the above statements, choose the correct answer from the options given below.
  1. A
    Both (A) and (R) are true and (R) is the correct explanation of (A).
  2. B
    Both (A) and (R) are true but (R) is not the correct explanation of (A).
  3. C
    (A) is true but (R) is false.
  4. D
    (A) is false but (R) is true.
