Pse isotope

WebA radioactive isotope, also known as a radioisotope, radionuclide, or radioactive nuclide, is any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, and gamma rays. WebStable isotope analysis is based on the principle ‘you are what you eat.' Stable isotope ratios vary among food webs and are incorporated into an animal's tissue via its diet (Hobson 1999). It...

WebOct 10, 2024 · Americium: Americium is a silvery metal, which corrodes slowly in air and is soluble in acid. It has the isotopes: Am-243, Am-242 and Am-241, with a half-life of 432 years, which was the first isotope to be isolated. The isotope Am-241 decays by emitting alpha particles and intense gamma radiation to become neptunium-237. WebOne interesting feature of fullerenes is their ability to enclose atoms such as potassium and other alkali metals to make endohedral structures denoted as K@C 60.
