Solution

The correct option is D
Statement 1 is not correct but Statement 2 is correct.

Option (D) is correct.
Statement 1 : Caesium is the most active metal in the first group of the Periodic Table because Cs has (a) the largest atomic radius, thus making it easier to lose its outer energy level electron, and (b) the intermediate electrons help screen the positive attraction of the nucleus, also increasing the ease with which the outer electron is lost.
Statement 1 : Lithium has only the electron in the outer energy level which is easily lost to form an ion with a single positive charge.
