Question

2003 Q 2 Study the information in the table and answer the questions that follow lon Electronic Ionic arrangement radius Na 2.8 0.095 K K 2.8.8 0.133 Mg? 2.8 0.065 Explain why the ionic radius of K* is greater than that of Na* ​

Answer 1

Hence

potassium (k) is 2,8,8,1

sodium (Na) is 2,8,1

potassium will have a higher Ionic radius than sodium

Step-by-step explanation:

Ionic radius has a trend

it increases down the group

and decreases across the period
