Q. Given two statements below :
Statement I : In $Cl _2$ molecule the covalent radius is double of the atomic radius of chlorine.
Statement II : Radius of anionic species is always greater than their parent atomic radius.
Choose the most appropriate answer from options given below :

Solution:

In $Cl _2$ molecule, the covalent radius is half of the internuclear distance, so statement(I) is false.
For the same element, anion has lower effective nuclear charge than atom $\Rightarrow$ so anion is larger than atom. $\Rightarrow$ statement (II) is correct.
