JEE Main Chemistry question

Statement 1: In any period, the radius of the noble gas is the lowest. Statement 2: He has the highest ionisation energy in the Periodic Table.

(A)Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1
(B)Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1
(C)Statement 1 is True, Statement 2 is False
(D)Statement 1 is False, Statement 2 is TrueCorrect

Answer: (D)

Solution

Statement 1 is false — in any period, the noble gas actually has the largest radius (measured by van der Waals radius), not the lowest, since it does not form bonds and its electron cloud extends further relative to the covalently-bonded atoms of the period.
