Periodic Table and Periodicity question

2021 · 31 Aug · Shift 1 · Q9

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) : Metallic character decreases and non-metallic character increases on moving from left to right in a period. Reason (R) : It is due to increase in ionisation enthalpy and decrease in electron gain enthalpy, when one moves from left to right in a period. In the light of the above statements, choose the most appropriate answer from the options given below :
  1. A
    (A) is false but (R) is true.
  2. B
    (A) is true but (R) is false
  3. C
    Both (A) and (R) are correct and (R) is the correct explanation of (A)
  4. D
    Both (A) and (R) are correct but (R) is not the correct explanation of (A)
