Solution

The correct option is D Statement I is incorrect, but Statement II is correct.
Option A is the correct answer.
Statement 2 is correct. Atomic number increases as one goes from left to right of a periodic table.
Statement 1 is not correct. Because, atomic radius decreases as one goes from left to right of a periodic table. As the atomic number increases, the number of electrons as well as protons both increases. The nuclear force of attraction on the outer electrons also increases rapidly and hence the atomic radius of the element decreases.

Q. Statement I: The

5^{t h}

period of the periodic table contains 18 elements and not 32.
Statement II:
