Strontium: Science-Based Facts vs Fiction
Strontium In A Nutshell. Strontium is a chemical element with the symbol Sr and the atomic number 38. You might remember it from chemistry class as part of the second column in the periodic table, the alkaline earth metals. In that column, it falls between calcium and barium, a proximity that reflects these elements' formal similarity.
