a metallic chemical element (symbol Sr) with an atomic number of 38
a soft silver-white or yellowish metallic element of the alkali metal group; turns yellow in air; occurs in celestite and strontianite
{i} (Sr) soft silvery metallic element (Chemistry)
A silvery-white metallic element, chemically similar to calcium
It is chiefly employed (as in the nitrate) to color pyrotechnic flames red
A trace element found in seawater that is required for corals and creatures with calcareous skeletons to grow Strontium levels can be maintained through regular water changes and by the use of strontium additives
A soft metal, it has a silvery lustre when freshly cut but reacts rapidly with air. In both the metal and the compounds (in which it has valence 2), strontium resembles calcium and barium so closely that it has few uses that the other two elements cannot supply more cheaply. The nitrate and chlorate, very volatile, give off brilliant crimson flames and are used in flares, fireworks, and tracer bullets. The radioactive isotope strontium-90 (see radioactivity), produced in nuclear explosions, is the principal health hazard in fallout; it can replace some of the calcium in foods, concentrate in bones and teeth, and cause radiation injury
Atomic weight 87
A metallic element of the calcium group, always naturally occurring combined, as in the minerals strontianite, celestite, etc
a soft silver-white metal that is used to make fireworks. It is a chemical element : symbol Sr (Strontian, village in Scotland where a substance formed from strontium was discovered). Chemical element, one of the alkaline earth metals, chemical symbol Sr, atomic number
Symbol Sr
This trace element is necessary for corals, clams, and other creatures with calcareous skeletons to grow It is most commonly added as strontium chloride SrCl2
It is isolated as a yellowish metal, somewhat malleable but harder than calcium

strontium-90
The radioactive isotope of strontium, 9038Sr, that is present in the fallout from nuclear explosions and, being chemically similar to calcium, is accumulated in the bones
strontium 90
The strontium isotope with mass 90, having a half-life of 28 years, used for its high-energy beta emission in certain nuclear electric power sources and constituting a radiation hazard in fallout
strontium 90
a radioactive isotope of strontium (with the mass number 90) that is present in the fallout from nuclear explosions; can be assimilated like calcium into bones
rubidium-strontium dating
geological dating based on the proportions of radioactive rubidium into its decay product strontium; radioactive rubidium has a half-life of 47,000,000,000 years
rubidium-strontium dating
Method of estimating the age of rocks, minerals, and meteorites from measurements of the amount of the stable isotope strontium-87 formed by the decay of the unstable isotope rubidium-87 that was present in the rock at the time of its formation. The method is applicable to very old rocks because the transformation is extremely slow: the half-life, or time required for half the initial quantity of rubidium-87 to disappear, is approximately 48.8 billion years.
