Question

Bond energy Bond polarity Percent ionic character. List the following bonds in order of increasing ionic character: the rubidiumt bond in RbF, the magnesium to oxygen bond in MgO, the nitrogen to nitrogen bond in N2, the phosphorus to fluorine bond in PFs, and the oxygen to fluorine bond in OF2 o fluorine W. 9. An ionic bond is formed between a cation A' and an anion B. Which of the following changes would result in a decrease in lattice energy for this compound? A. Doubling the radius of A B. Tripling the charge on A. C. Doubling the charge on A' and B-. D. Decreasing the radii of A and B to half their original values.

Explanation / Answer

As we know that Rb is the 5th period element in 1st group that is alkali metal group.

So its size is larger so that outermost shell electrons are loosely bound. On the other side F is most electronegative element so it attracts the loosely bound electrons of Rb. As a result partial negative and positive charges are generated resulting in highly ionic bond..
