![]() But it is always found as a compound with other elements. Strontium is a reactive chemical element, and hence it is not found in a free state in nature.Chemical properties of StrontiumĬhemical properties of strontium are mentioned below. Out of them, 88Sr is the most abundant (around 82.5 %). Strontium has many isotopes including stable isotopes as well as radioactive isotopes.The melting point of strontium is 777 ☌ and its boiling point is 1377 ☌.The atomic mass of strontium is 87.62 u and its density is 2.63 g/cm 3.Strontium is a soft metal having a silvery metallic surface with yellow tint.Physical properties of strontium are mentioned below. The physical and chemical properties of strontium element are mentioned below. The nonradioactive isotopes of strontium are non-toxic.Strontium is classified as an “Alkaline earth metal” on the periodic table as it forms an alkaline solution on reacting with water, plus strontium is obtained from the earth.Hence it is kept under kerosene or mineral oil. Strontium is reactive even in the open atmosphere.Most of the strontium metal is extracted from its ore strontianite and celestite.In the entire world, approximately 3 lakh tons of strontium is produced annually.China and Spain are the leading producers of strontium in the world.Amount of strontium present in earth’s crust is around 360 ppm (parts per million).Strontium is mostly obtained from the earth’s crust and it is the 15 th most abundant element found from the earth’s crust.Interesting facts about strontium element are mentioned below. So the last electron of strontium enters the s-subshell or s-orbital. The simple answer: The elements will lie in the s, p, d or f block will completely depend upon the subshell in which the last electron will enter.įor example the electron configuration of strontium is 5s 2.
