The ionic radius of two ions A+ and B- is 88PM and 200PM respectively. If AB is closed packed crystal, then determine the coordination number of A+ ion.?
Most Upvoted Answer
The ionic radius of two ions A+ and B- is 88PM and 200PM respectively....
Explanation:
Definition: The coordination number of an ion is the number of ions of opposite charge surrounding it in a crystal lattice.
Given that the ionic radius of ion A is 88PM and the ionic radius of ion B- is 200PM. Therefore, the radius ratio is 88/200 = 0.44.
Radius Ratio Rule: It states that the coordination number of a cation in an ionic crystal is determined by the ratio of the radius of the cation to the radius of the anion.
Since the AB crystal is a closed packed structure, the anion B- forms a close-packed arrangement, and the cation A fits into the octahedral holes between the anions in a close-packed arrangement. Therefore, the coordination number of A ion will be 6.
Conclusion: The coordination number of A ion is 6.
