strontium, Sr, atomic number 38(noun)
a soft silver-white or yellowish metallic element of the alkali metal group; turns yellow in air; occurs in celestite and strontianite
a metallic chemical element (symbol Sr) with an atomic number of 38.
Origin: From the name of the Scottish town Strontian
a metallic element of the calcium group, always naturally occurring combined, as in the minerals strontianite, celestite, etc. It is isolated as a yellowish metal, somewhat malleable but harder than calcium. It is chiefly employed (as in the nitrate) to color pyrotechnic flames red. Symbol Sr. Atomic weight 87.3
a radioactive isotope of strontium produced by certain nuclear reactions, and constituting one of the prominent harmful components of radioactive fallout from nuclear explosions; also called radiostrontium. It has a half-life of 28 years
Origin: [NL. See Strontia.]
Strontium is a chemical element with symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silver-white or yellowish metallic element that is highly reactive chemically. The metal turns yellow when exposed to air. Strontium has physical and chemical properties similar to its two neighbors calcium and barium. It occurs naturally in the minerals celestine and strontianite. While natural strontium is stable, the synthetic 90Sr isotope is present in radioactive fallout and has a half-life of 28.90 years. Both strontium and strontianite are named after Strontian, a village in Scotland near which the mineral was first discovered in 1790 by Adair Crawford and William Cruickshank. The production of sugar from sugar beet was in the 19th century the largest application. Strontium compounds are today mostly used for the production of cathode ray tubes. The displacement of cathode ray tubes by other display methods in television sets is changing the overall consumption.
Chambers 20th Century Dictionary
stron′shi-um, n. a yellowish, ductile, malleable metal somewhat harder than lead, existing as a carbonate in the mineral Strontianite (first found in 1790 near Strontian in Argyllshire), and as a sulphate in the mineral known as Celestine.—ns. Stron′tia, the oxide of strontium—also Stron′tian; Stron′tianite, carbonate of strontia.
U.S. National Library of Medicine

An element with a known symbol and atomic number.

Examples of strontium in a Sentence
A: Strontium 90, Carbon 14 Q: What was the score of the last Strontium / Carbon game?
In areas with farming, one should be very careful when using strontium isotopes to trace the origin and movement of prehistoric people.
Unfortunately, it was not possible to examine the strontium isotope ratio of the remaining individuals, because the teeth were too decayed and the result would have been distorted.
We felt it odd that the maps of strontium distributions on which these conclusions were based show no resemblance to the underlying geology, we set out to test if modern-day farming could be the reason that the natural strontium variations were obscured.
When it comes to light chemical elements( such as carbon and oxygen), these are heavily altered but for heavier elements such as strontium no alteration was observed, on the contrary, thanks to the high temperatures reached, the structure of the bone is modified and making the bone resistant to post-mortem exchanges with burial soil.
