Strontium komt in zijn elementaire vorm van nature in veel delen van het milieu voor, waaronder de rotsen, de bodem, het water en de lucht. Strontiummengsels kunnen zich zeer gemakkelijk door het milieu verplaatsen, omdat veel van deze mengsels wateroplosbaar zijn In general, the chemistry of strontium is quite similar to that of calcium. In its compounds strontium has an exclusive oxidation state of +2, as the Sr 2+ ion. The metal is an active reducing agent and readily reacts with halogens, oxygen, and sulfur to yield halides, oxide, and sulfide Strontium ist mit einem Anteil von 370 ppm an der kontinentalen Erdkruste auf der Erde verhältnismäßig häufig, die Elementhäufigkeit in der Erdkruste ist vergleichbar mit der von Barium, Schwefel oder Kohlenstoff.Auch im Meerwasser ist eine größere Menge Strontium vorhanden.

Strontium is the chemical element with the symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly chemically reactive.The metal forms a dark oxide layer when it is exposed to air. Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, calcium and barium Strontium-90, a radioactive isotope of strontium, is a common product of nuclear explosions. It has a half-life of about 28.8 years and decays into yttrium-90 through beta decay. Strontium-90 is especially deadly since it has a relatively long half-life, is strongly radioactive and is absorbed by the body, where it accumulates in the skeletal system

Strontium isotopic ratios are widely used as tracers in geological processes and as indicators of provenance in an archaeological context. A significant fraction of the Earth's 87 Sr is not primordial, but is produced by the decay of 87 Rb. Geochemically, Strontium follows Calcium, while Rubidium follows Potassium; thus, the geological variability of Sr isotope ratios in rocks is a function.

LOCAL ENVIRONMENT OF STRONTIUM IONS 267 with no phase shift correction are shown in Fig. 2b. The FT of the spectrum of st rontianite strongly differs from those described in the literature [14, 22. Since the magnitude of the charges on these two ions are equal, they react on a 1 : 1 mole ratio, meaning one molecule should have one strontium ion to one oxide ion, The correct formula is {eq. High Accuracy Strontium Ion Optical Clock Helen Margolis, Geoff Barwood, Hugh Klein, Guilong Huang, Stephen Lea, Krzysztof Szymaniec and Patrick Gill T&F Club 15th April 2005. Outlin ^ Rin Dee did a good job of answering the question(s). The concise answer is Strontium ion has a +2 charge & you can determine the number of valence electrons by looking at which group the element in question is in. Strontium is in Group 2 & therefore has 2 v e- 1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(2)4p^(6) Strontium is atomic number 38 so its electron configuration can be written: 2.8.18.8.2 In orbital notation this is: 1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(2)4p^(6)5s^(2) The noble gas shorthand notation is: [Kr]5s^(2) When strontium forms a 2+ ion the 2 outer 5s electrons are lost so Sr^(2+) can be written as: 1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d.
