JEE Main 5 April 2024, Shift 2, Chemistry Q66

Question 66 of 90 in this shift, Chemistry question 6 of 30, Section A.

Given below are two statements : Statement I : The metallic radius of Na is 1.86 A∘1.86\ \mathrm{A^\circ} and the ionic radius of Na+\mathrm{Na^+} is lesser than 1.86 A∘1.86\ \mathrm{A^\circ}. Statement II : Ions are always smaller in size than the corresponding elements. In the light of the above statements, choose the correct answer from the options given below :
  1. (1)Both Statement I and Statement II are true
  2. (2)Both Statement I and Statement II are false
  3. (3)Statement I is correct but Statement II is falseOfficial answer
  4. (4)Statement I is incorrect but Statement II is true
