Strontium is a chemical element; it has symbol Sr and atomic number 38. ... The Sr 2+ ion is quite large, ...
The ratio 87 Sr/ 86 Sr is the parameter typically reported in geologic investigations; [4] ratios in minerals and rocks have values ranging from about 0.7 to greater than 4.0 (see rubidium–strontium dating). Because strontium has an electron configuration similar to that of calcium, it readily substitutes for calcium in minerals.
Strontium nitrate is an inorganic compound composed of the elements strontium, ... As a divalent ion with an ionic radius similar to that of Ca 2+ ...
Strontium chloride is a precursor to other compounds of strontium, such as yellow strontium chromate, strontium carbonate, and strontium sulfate. Exposure of aqueous solutions of strontium chloride to the sodium salt of the desired anion often leads to formation of the solid precipitate: [9] [2] SrCl 2 + Na 2 CrO 4 → SrCrO 4 + 2 NaCl
Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, ... strontium: 38 (4 ticks)
It is a tabular arrangement of the elements by their chemical properties that usually uses abbreviated chemical symbols in place of ... Strontium [ax] 2 5 s-block 87. ...
The first molar ionization energy applies to the neutral atoms. The second, third, etc., molar ionization energy applies to the further removal of an electron from a singly, doubly, etc., charged ion. For ionization energies measured in the unit eV, see Ionization energies of the elements (data page). All data from rutherfordium onwards is ...
A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+. The solvation number , n , determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table .
