Strontium Side Effects are Overblown - Get the Facts!
Strontium Ranelate Drug Strontium’s beneficial effects in the treatment of osteoporosis were reported way back in 1910 — but strontium products never entered the market back then due to confusion between the normal, stable forms of strontium with its radioactive isotopes. isotopes.
Strontium | Sr - PubChem
Strontium is a naturally occurring element found in rocks, soil, dust, coal, and oil. Naturally occurring strontium is not radioactive and is either referred to as stable strontium or strontium.Strontium in the environment exists in four stable isotopes, 84 Sr (read as strontium eighty-four), 86 Sr, 87 Sr, 88 Sr. Strontium compounds are used in making ceramics and glass products, pyrotechnics

Periodic Trends in Atomic Size - Chemistry | Socratic
Periodic trends predict differences between elemental characteristics as you move across the periodic table. Trends are based on Coulo''s law which mathematically relates several characteristics of an elements. Atomic size measured the distance between the nucleus of an atom and the outermost non-valence electrons of the atom. Atomic size decreases from left to right, because the addition of
