Strontium is a solid at room temperature.
Explanation: Strontium is a chemical element with the symbol Sr and atomic number 38. It belongs to the alkaline earth metals group in the periodic table. At room temperature, which is generally considered to be about 20-25 degrees Celsius (68-77 degrees Fahrenheit), strontium exists as a shiny, silvery-white metal. Like other metals, it has a crystalline structure and exhibits typical metallic properties such as conductivity and malleability. Strontium has a melting point of about 777 degrees Celsius, so it remains solid under normal conditions we encounter in daily life.
