Question

what is the difference between atomic radii and ionic radii

Answer 1

Simple!!

Atomic Radii :-
atomic radii is radius of atom from the outermost electron to Nucleus.

for eg :-

radius of Ca , Mg , Al

but ,



Ionic :- ( may be +ve ion or negative ion ) :- radius of valance electron to their nucleus


simple term, ion means ion is form so that ionic radii may or may not be greater than radii of atom.


For eg :-

Ca 2+


the radii of this ion is less than the original original atomic radii.


but , Ca2-

this ion have more ionic radii as compared to original atomic radii.


so there is difference between:- ionic Radii and Atomic radii




hope it help you!!


thanks!
