Question

Which is large na+ or k+ ? Why?

Answer 1

I don't know on which basis are you asking this question but I am answering on the basis of atomic radius Na has 3 shells in it and to form Na+ it will lose the last electrons from its last shell and then in its last third shell no electron would be left out so it will have two shells where as in potassium came has four shells and two from K + it will lose the last electron from its last shell and that it last shell will be left out of no electrons hence it would be left out with its three shells so Here k+ is has a larger atomic radii than in a plus
