Question

What is the most stable oxide of Fr?

Answer 1

Superoxides of K, Rb and Cs are most stable. Larger cations are stabilized by larger anions due to higher lattice energies.The anion sizes in increasing order are oxide < peroxide < superoxide, so lithium forms the most stable oxide, sodium the most stableperoxide and superoxide is the most stable form for the rest.

Answer 2

HERE IS YOUR ANSWER..⤵⤵⤵


➡"Fr" means "Francium" .It is the heaviest alkali metal.It is a highly radioactive metal that decays into astatine, radium, and radon.

▶The most stable oxide of "Fr" is Fr2O.

➡Because "Fr" presumably behaves the se way as all the other matallic members of group 1.
