Question

Why are chlorine anions larger than chlorine atoms?

Answer 1

Chlorine anion, or chloride ion, on the other hand, since it has accepted 1 electron to achieve stable octet arrangement, it has 8 electrons in the outermost shell. ... An Na+ ion is smaller than an Na atom while a Cl-ion is bigger than a Cl atom.

Answer 2

Explanation:

${ \huge{ \texttt{ \fcolorbox{lightgreen}{black}{Aɳʂɯҽr}}}}$

Chlorine has a proton number of 17. ... Hence, we can deduce that the forces of attraction exerted on the outermost electron in chloride ion is lesser than chlorine atom, since there are more electrons. Conclusion, chloride ion has a bigger atomic radius due to an increase in number of electrons
