The green color denotes the presence of the element boron (B) which you'd expect in boric acid. The cream of tartar yielded a purple-colored flame. Purple is associated with the presence of potassium (K). That's because cream of tartar is a potassium salt. These element-specific colors are catalogued in an emission spectrum.

If strontium is found to be an essential trace mineral, the RDA will be about 1 mg. Sodium Sodium is an essential major mineral and is an antagonist to phosphorus and potassium. Sodium and potassium are the most important electrolyte minerals in the body fluids.
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.
barium, calcium, magnesium, potassium, sodium, and strontium) in most samples of surficial materials from the Eastern United States, and the greater abundance of heavy metals in the same materials of the Western United States, indicates a regional geochemical pat- tern of the largest scale. The low concentrations of many elements

Strontium may be obtained in the form of sticks by the contact cathode method of electrolysis, in which a cooled iron rod, acting as a cathode, just touches the surface of a fused mixture of potassium and strontium chlorides and is raised as the strontium solidifies on it.
Explanation. Step 1. 1 of 2. Compare electronegativity. Electronegativity values range from 0.7 to 4.0, and elements with lowest and highest electronegativities are the most reactive. Potassium, calcium, iron and copper are all in fourth period, and electronegativity increases from left to right in a period. From the given elements, potassium ...

May 05, 2020· (Strontium may remain in the bones for as long as 7–10 years after the last dose.) Strontium has a chemical similarity to calcium and will replace calcium as the mineral in bone. Because strontium atoms are heavier than calcium atoms, swapping some of the calcium atoms with strontium atoms will make the bone mineral density appear to increase.
