What is Strontium as on the Periodic Table? Definition of the Strontium Element
A soft, silvery, easily oxidized metallic element that ignites spontaneously in air when finely divided. Strontium reacts vigorously with water and quickly tarnishes in air, so it must be stored out of contact with air and water.

Due to its extreme reactivity to air, this element always naturally occurs combined with other elements and compounds. Strontium is used in pyrotechnic compounds and various alloys. The Atomic Number of this element is 38 and the Element Symbol is Sr.

 

What is Strontium? Origin / Meaning of the name Strontium
This was named after the Scottish town of Strontian because the mineral strontianite is found in mines in Strontian.

What is Strontium? Periodic Table Group and Classification of the Strontium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Strontium is classified as an "Alkaline Earth Metals" which are located in Group 2 elements of the Periodic Table. An Element classified as an Alkaline Earth Metals are found in the Earths crust, but not in the elemental form as they are so reactive. Instead, they are widely distributed in rock structures. Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals.

Common properties of Alkaline Earth metals
The elements classed as "Alkaline Earth metals" have the following properties in common:

  • Shiny Solids
  • Two electrons in the outer shell
  • Can conduct heat or electricity
  • Can be formed into sheets

What is Strontium? Occurrence of the Strontium Element
Strontium occurs sparingly in nature, usually as strontianite (SrCO3) and as celestite (SrSO4). Both minerals form beautiful colorless crystals, though celestite is sometimes colored a faint blue. Only a few of the compounds of strontium have any commercial applications.
Obtained from celestite and strontianite
Found in 0.034% of all igneous rock in the form of the sulphate mineral celestite and the carbonate strontianite

Abundances of the element in different environments

Facts about the History of the Discovery of Strontium Element
The mineral strontianite was recognised by Adair Crawford in 1790 and it was named after the Scottish town of Strontian. Klaproth and Hope discovered strontium itself in 1798 and the metallic strontium was first isolated by Sir Humphry Davy in 1808 by the use of electrolysis. It does not occur naturally, is very soft and scratches easily.

Sir Humphry Davy
Sir Humphry Davy (1778-1829) isolated
Sodium, Lithium, Potassium, barium, strontium, and Calcium by means of electrolysis. Davy also demonstrated the elementary nature of Chlorine, invented the safety lamp and discovered the stupefying effects of nitrous oxide.

Sir Humphry Davy (1778 - 1829)

What is Strontium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day in his day but still all fitting into his concept of  the "Periodic Table" in which Strontium is just one element that can be found.
