👉 In physics, a strontium (Sr) is a naturally occurring radioactive element with the atomic number 80. It has the chemical symbol Sr and its name derives from the Latin word "stronatus," meaning "heavy." Strontium is known for its high radioactivity and is used in various applications such as nuclear medicine, neutron scattering, and medical imaging. Strontium has a relatively short half-life, which means that it decays into two isotopes within 10
