Sodium Element Facts - Periodic table

Sodium burns in air with a brilliant yellow flame. Sodium floats on water, because its density is lower than water’s. It also reacts vigorously with water – violently if more than a small amount of sodium meets water (see video on left) – to produce sodium hydroxide and hydrogen gas.

Strontium - Wikipedia

Strontium metal burns in air to produce both strontium oxide and strontium nitride, but since it does not react with nitrogen below 380 C, at room temperature, it forms only the oxide spontaneously. Besides the simple oxide SrO, the peroxide SrO 2 can be made by direct oxidation of strontium metal under a high pressure of oxygen, and there is some evidence for a yellow superoxide Sr(O 2 ) 2 .
