Answer:
Sodium Chloride has stronger ionic attraction than Potassium Chloride .
Step-by-step explanation:
The radius of sodium ion = 102 pm
The radius of Potassium ion = 138 pm
From the given data , the radius of sodium ion is smaller than that of potassium ion .
Hence ,
Due to the smaller size of sodium ion , it will bind with stronger force of attraction with the chloride ion ,
as compared to potassium ion binding with the chloride ion , due to its larger size .
Hence ,
Sodium Chloride has stronger ionic attraction than Potassium Chloride .
