Question

5. Ion Ionic radius (pm) 74 100 135 Zn2+ Ca2+ Based on the data in the table above, which of the following correctly predicts the relative strength of the attraction of Zn2, Ca2, and Ba+ ions to chloride ions in a crystal, from strongest to weakest, and provides the correct reason? a. Zn2+Ca2 Bbecause the smaller ions have a stronger coulombic attraction to chloride ions b. Zn2+>Ca2* > Ba2+ because the smaller ions are more electronegative c. Ba2+> Ca2+>Zn2+ because the larger ions are more polarizable d. Ba2+>Ca2+>Zn2+ because the larger ions are less electronegative 2 Nitrogen (N)

Explanation / Answer

Correct option is d.

Because larger the size , easily donate electrons and form strong bond with chlorine
