Question
Statement I: In Cl2 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
The options for the answer are not provided, but I can explain the statements for you.
Statement I: In a Cl2 molecule, the covalent radius is indeed roughly half the distance between the two nuclei of the chlorine atoms. This is because the covalent radius is defined as half the distance between the nuclei of two identical atoms bonded together. So, this statement is true.
Statement II: The radius of an anionic species is generally larger than their parent atomic radius. This is because when an atom gains an electron to become an anion, the increased electron-electron repulsion causes the electron cloud to expand and hence the atomic radius increases. So, this statement is also true.
Without the options, I can't provide the most appropriate answer, but both statements are correct.
