Strontium nitrate significantly better than using glycolic acid alone. As a divalent ion with an ionic radius similar to that of Ca (1.13 vs. 0.99 A, respectively), Sr ions resembles calcium's ability to traverse calcium-selective ion channels and trigger neurotransmitter release from nerve endings. It is thus used in electrophysiology experiments. In his short story "A Germ Destroyer", Rudyard Kipling refers to strontium nitrate as the main ingredient of the titular fumigant. Strontium nitrate Strontium nitrate is an inorganic compound made of the elements strontium and nitrogen with the formula Sr(NO). This colorless solid is used as a red colorant and oxidizer
Period 2 element protons and six neutrons. C is also stable, with six protons and seven neutrons, at 1.1%. Trace amounts of C also occur naturally but this isotope is radioactive and decays with a half life of 5730 years; it is used for radiocarbon dating. Other isotopes of carbon have also been synthesised. Carbon forms covalent bonds with other non-metals with an oxidation state of −4, −2, +2 or +4. Carbon is the fourth most abundant element in the universe by mass after hydrogen, helium and oxygen and is the second most abundant element in the human body by mass after oxygen,
