Which of the following pairs would have a the
larger size
K or k+ ?
Explain your
ur answer.

Here u go!

Explanation:

In other words, "K"^(+) has bigger effective nuclear charge than "Cl"^(-), which translates to a bigger net positive charge felt by the outermost electrons. This will compress the energy levels a bit and make the ionic radius smaller for the potassium cation. Therefore, the chloride anion will have the larger atomic radius.

Hope this helps ma dude!

i have no clue hope you find the answer
