Sodium Peroxide Formula: Sodium (Na) is classified as an alkali metal, featuring an atomic number of 11 on the periodic table. This highly reactive, soft, silvery-white metal contrasts with oxygen (O), which hold an atomic number of 8. Oxygen, in its role as a highly reactive nonmetal and oxidant, readily forms oxides with various elements and compounds.
Sodium peroxide, with the chemical formula Na₂O₂, is an inorganic compound. This solid substance, tinted yellow, is the result of igniting sodium in an oxygen-rich environment. It holds strong alkaline properties.

Disodium dioxide appears as a granular solid with a color spectrum ranging from yellow-white to yellow. When it comes into contact with any combustible substance. it readily ignites when exposed to heat, moisture, or friction. Upon longer exposure to heat. it undergoes a highly energetic decomposition process. On a larger industrial scale. Disodium dioxide can be produced by subjecting metallic sodium to oxygen within a temperature range of 130 to 200 °C. Sodium Peroxide boasts a crystalline hexagonal structure.
