Answer 1

$\huge\mathbb\red{a}\purple{n}\green{s}\blue{w}\red{e}\purple{r}$

Lithium (and to some extent sodium) form simple oxides, X2O, which contain the common O2− ion .

Sodium (and to some extent potassium) form peroxides, X2O2, containing the more complicated O2−2 ion.

Potassium, rubidium and cesium form superoxides, XO2.

Answer 2

Answer:

The oxide forms of each element can be summarized as follows:

Lithium (and to some extent sodium) form simple oxides, X2O, which contain the common O2− ion .

Sodium (and to some extent potassium) form peroxides, X2O2, containing the more complicated O2−2 ion.

Potassium, rubidium and cesium form superoxides, XO2.
