Question

Compare the atomic size of chlorine atom (CL) and chloride ion (CL-)

Answer 1

Answer:

This question is not from physics bro .But still:-

Explanation:

size of chlorine atom is larger than size of chloride ion

Answer 2

Detailed answer is given below.

We have to compare The atomic size of $Cl$ and $Cl^-$ ion .

We know, chlorine is very electronegative atom and it have highest electron affinity as compared to all other elements in atomic table .

Also, chlorine atom have 17 electron.

When chlorine atom gain an electron it forms $Cl^-$ ions total number of electrons in ion increases to 18 .

After gain of electron the inter electronic repulsion between every electrons increases , which cause the increase in separation between electrons and effectively increase the atomic size of $Cl^-$ ion .

Hence , this is the required solution.
