what are the metals among the strontium using method

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 . [10]
