Let be the number of alkali metals that form superoxides as their major product when heated in exces — s Block Elements Chemistry Question

💡 Solution & Explanation

The alkali metals that form superoxides as their major product are K, Rb, and Cs, so $x = 3$. The superoxide ion ($O_2^-$) has a 3-electron covalent bond with exactly 1 unpaired electron (paramagnetic), so $y = 1$. The product $3 \times 1 = 3$.
