Question
Chapter 2, Problem 2.100P
Interpretation Introduction
Interpretation:A pair should be selected that gives strongest ionic bonding and a pair that gives weakest ionic bonding from the following ions with their radii:
Concept Introduction:The ionic bond forms due to complete transfer of electron(s) from one atom to another. The atom losing electron(s) is said to be cation whereas the atom gaining electron(s) is said to be anion. The interaction is strong due to opposite ions.
