Question

the ionic radii of potassium ion and F minus are nearly same that is 1.34 m strums then the atomic radii of potassium and F respectively are​

Answer 1

Question: If the ionic radii of K+ and F- are nearly the same (i.e, 1.34              angstrom), then the atomic radii of K and F respectively are :

1) 1.34 °A , 1.34 °A

2) 0.72 °A , 1.96 °A

3) 1.96 °A , 0.72 °A

4) 1.96 °A , 1.34 °A

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

Correct your question and mark me brainliest plz.
