Question

ionic radii of K plus and F minus R about 1.34 Armstrong each then the expected values of atomic radius of K and F should be respectively​

Answer 1

Answer:

The cationic radius is smaller than the atomic radius. Whereas the anionic radius is larger than the atomic radius.The atomic radius of K will be 1.96 A0which will be larger than 1.34 A0 (the ionic radius of K+).The atomic radius of F will be 0.72A0 which will be smaller than 1.34A0 (the ionic radius of F−

Answer 2

Answer:

if any atom loss electron then their radius will be decrease so , it means radius of atom k has more value then k+ ion

and if any atom gain electron then their size increases it means radius of F atom is smaller then F- ion

now due to above conclusion , option(3) is correct answer .
