Question

Potassium, Rubidium and cesium also form compounds that contain the O₂¹⁻ ion, which we call the superoxide ion.

A. True
B. False

Answer 1

True. Potassium, rubidium, and cesium can form compounds that contain the superoxide ion (O₂¹⁻). Examples of superoxides include KO₂, RbO₂, and CsO₂, which are formed when these metals react with excess oxygen.

Step-by-step explanation:

True. Potassium, rubidium, and cesium can all form compounds that contain the superoxide ion (O₂¹⁻). Superoxides are compounds in which the oxygen atom has a charge of -1/2.

Examples of superoxides include KO₂, RbO₂, and CsO₂, which are formed when these metals react with excess oxygen.
