(Redirected from Alkali metal oxide)
A sample of sodium peroxide.
The alkali metals react with oxygen to form several different compounds: suboxides, oxides, peroxides, sesquioxides, superoxides, and ozonides. They all react violently with water.
Alkali metal suboxides[edit]
Structure of undecacaesium trioxide.
Alkali metal oxides[edit]
Crystal structure of rubidium oxide.
-
Lithium oxide (Li2O) is the lightest alkali metal oxide and a white solid. It melts at 1570 °C.
-
Sodium oxide (Na2O) is a white solid that melts at 1132 °C and decomposes at 1950 °C. It is a component of glass.
-
Potassium oxide (K2O) is a pale yellow solid that decomposes at 350 °C.
-
Rubidium oxide (Rb2O) is a yellow solid that melts at 500 °C.
-
Caesium oxide (Cs2O) is a yellow-orange solid that melts at 490 °C.
Alkali metal peroxides[edit]
Crystal structure of sodium peroxide.
Alkali metal sesquioxides[edit]
Alkali metal superoxides[edit]
Crystal structure of potassium superoxide.
Alkali metal ozonides[edit]
Crystal structure of caesium ozonide.
-
Lithium ozonide (LiO3) is a red solid which is produced from caesium ozonide via an ion-exchange process.
-
Sodium ozonide (NaO3) is a red solid which is produced from caesium ozonide via an ion-exchange process.[1]
-
Potassium ozonide (KO3) is a dark red solid which is produced when potassium is burned in ozone or exposed to air for years.
-
Rubidium ozonide (RbO3) is a dark red solid which is produced when rubidium is burned in ozone.
-
Caesium ozonide (CsO3) is a dark red solid which is produced when caesium is burned in ozone.[2]
