Strontium (Sr) - Periodic Table

Strontium. (Sr) From Wikipedia, the free encyclopedia 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. …

Strontium - Element, Uses, Compounds

Strontium is a chemical element or alkaline earth metal found in group 2 of the periodic table with the symbol Sr and atomic number 38. It is a silvery white, lustrous, soft metallic element. However, strontium is much harder than alkali metals due to the presence of two valence electrons for metallic bonding.

Strontium (Sr) - ISOFLEX USA

Request a Quote. Strontium was discovered in 1790 by Adair Crawford. It is named for the village of Strontian in Scotland. A silvery-white metal when freshly cut, strontium rapidly turns yellow on exposure to air, forming a thin oxide coating. It has a face-centered cubic structure, is malleable and ductile, and is chemically similar to calcium.

Strontium - chemeurope

The alkali earth metal strontium has four stable, naturally occurring isotopes: 84 Sr (0.56%), 86 Sr (9.86%), 87 Sr (7.0%) and 88 Sr (82.58%). Only 87 Sr is radiogenic; it is produced by decay from the radioactive alkali metal 87 Rb, which has a half-life of 4.88 × 10 10 years. Thus, there are two sources of 87 Sr in any material: that formed during primordial nucleo-synthesis along with …

Strontium | Public Health Statement | ATSDR

Strontium is a natural and commonly occurring element. Strontium can exist in two oxidation states: 0 and +2. Under normal environmental conditions, only the +2 oxidation state is stable enough to be important. Pure strontium is a hard, white-colored metal, but this form is not found in the environment. Rather, strontium is usually found in nature in the form of minerals.

Strontium (Sr) - Chemical properties, Health and Environmental …

Strontium is a soft, silver-yellow, alkaline-earth metal. It has three allotropic crystalline forms and in its physical and chemical properties it is similar to calcium and barium. 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 ...

Strontium (Sr) - Properties, Facts & Uses of Strontium …

Properties of Strontium. It has an atomic number of 38, an atomic mass of 88, one oxidation state (+2) and four naturally occurring isotopes ( 84 Sr, 86 Sr, 87 Sr, 88 Sr), of which 88Sr is the most abundant at 82.6% of the total mass. Strontium is most similar chemically to the heavier alkali earth elements, Calcium, and Barium.

Hair usually reflects the body burden of Strontium (Sr), and Sr levels usually correlate with calcium levels in body tissue. However, hair levels of Sr can be raised by external contamination, usually from hair treatment products. Elevated Sr in hair treated with permanent solutions, dyes, or bleaches is likely to be an artifact of hair ...

Sr-90 can be inhaled, but ingestion in food and water is the greatest health concern. Once in the body, Sr-90 acts like calcium and is readily incorporated into bones and teeth, where it can cause cancers of the bone, bone marrow, and soft tissues around the bone. Sr-90 decays to yttrium 90 (Y-90), which in turn decays by beta radiation so that ...
