Question

The radius of potassium atim is 0.203nm. The radius of potassium ion in nanometer will be

Answer 1

Answer:

0.133nm

Explanation:

Its atomic radius is 0.235 nm and the (+1) ionic radius is 0.133 nm. In the solid state Potassium has a body-centered cubic crystal structure with a = 0.533 nm and a nearest neighbor distance of 0.277 nm.

Answer 2

Answer:

0.133 nm

Explanation:

As the atomic radius of a metal is generally larger than the ionic radius of the same element

Here, as potassium is a metal hence,it's ionic radius is less than it's atomic radius
