Is strontium phosphide flammable?
Strontium phosphide is a solid which will evolve flammable and toxic gases on contact with water. It is a highly reactive material used as a laboratory reagent and in the manufacture of chemically reactive devices.
Is a phosphide a reducing agent?
STRONTIUM PHOSPHIDE is a reducing agent. They slowly generate flammable or noxious gases in contact with water. Phosphides react quickly upon contact with moisture or acids to give the very toxic gas phosphine; phosphides also can react vigorously with oxidizing materials. In general, materials in this group are incompatible with oxidizers such as atmospheric oxygen. They are violently incompatible with acids, particularly oxidizing acids.
What is the composition of strontium?
Natural strontium is a mixture of four stable isotopes: 84 Sr, 86 Sr, 87 Sr, and 88 Sr. Their abundance increases with increasing mass number and the heaviest, 88 Sr, makes up about 82.6% of all natural strontium, though the abundance varies due to the production of radiogenic 87 Sr as the daughter of long-lived beta-decaying 87 Rb. This is the basis of rubidium–strontium dating. Of the unstable isotopes, the primary decay mode of the isotopes lighter than 85 Sr is electron capture or positron emission to isotopes of rubidium, and that of the isotopes heavier than 88 Sr is electron emission to isotopes of yttrium. Of special note are 89 Sr and 90 Sr. The former has a half-life of 50.6 days and is used to treat bone cancer due to strontium's chemical similarity and hence ability to replace calcium. While 90 Sr (half-life 28.90 years) has been used similarly, it is also an isotope of concern in fallout from nuclear weapons and nuclear accidents due to its production as a fission product. Its presence in bones can cause bone cancer, cancer of nearby tissues, and leukemia. The 1986 Chernobyl nuclear accident contaminated about 30,000 km 2 with greater than 10 kBq/m 2 with 90 Sr, which accounts for about 5% of the 90 Sr which was in the reactor core.
Where is strontium found?
Strontium commonly occurs in nature, being the 15th most abundant element on Earth (its heavier congener barium being the 14th), estimated to average approximately 360 parts per million in the Earth's crust and is found chiefly as the sulfate mineral celestine ( SrSO 4) and the carbonate strontianite (SrCO 3 ). Of the two, celestine occurs much more frequently in deposits of sufficient size for mining. Because strontium is used most often in the carbonate form, strontianite would be the more useful of the two common minerals, but few deposits have been discovered that are suitable for development. Because of the way it reacts with air and water, strontium only exists in nature when combined to form minerals. Naturally occurring strontium is stable, but its synthetic isotope Sr-90 is only produced by nuclear fallout.
Is strontium a metal?
Strontium is a divalent silvery metal with a pale yellow tint whose properties are mostly intermediate between and similar to those of its group neighbors calcium and barium. It is softer than calcium and harder than barium. Its melting (777 °C) and boiling (1377 °C) points are lower than those of calcium (842 °C and 1484 °C respectively); barium continues this downward trend in the melting point (727 °C), but not in the boiling point (1900 °C). The density of strontium (2.64 g/cm 3) is similarly intermediate between those of calcium (1.54 g/cm 3) and barium (3.594 g/cm 3 ). Three allotropes of metallic strontium exist, with transition points at 235 and 540 °C.
Is strontium 90 radioactive?
Strontium-90 is radioactive and is a byproduct produced by nuclear reactors used in nuclear power. It is a component of nuclear waste and spent nuclear fuel. The half life is long, around 30 years, and is classified as high-level waste. It can take hundreds of years to decay to negligible levels. Exposure from contaminated water and food may increase the risk of leukimia, bone cancer and primary hyperparathyroidism.
What is the chemical formula for strontium phosphate?

Right from Wikepeida just for you: Strontium. Strontium is the chemical element with symbol Sr and atomic number 38.
What is the valence of strontium sulfate?
Strontium is a group 2 alkali-earth metal so it has a valence of +2 in compounds (like calcium). The sulfite ion, like the sulfate ion has a charge of -2. Therefor the chemical formula for strontium sulfite (SrSO3) follows the same rules as calcium sulfate (CaSO4) more commonly known as plaster of paris. 54 views.
Which element is in Group 2?
First, find the elements that make up the compound in the periodic table: strontium is an alkaline earth metal in Group 2 (2nd column) and phosphorus is in Group 15. Strontium will form an ion with a +2 charge and phosphorus will form an ion with a -3 charge. Sr2+ and P3-.
Is strontium a metal?
An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly reactive chemically. 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.
Is strontium radioactive?
While natural strontium is stable, the synthetic ⁹⁰Sr isotope is radioactive and is one of the most dangerous components of nuclear fallout, as strontium is absorbed by the body in a similar manner to calcium. Natural stable strontium, on the other hand, is not hazardous to health.
