WebNaturally occurring cobalt (27 Co) consists of a single stable isotope, 59 Co. Twenty-eight radioisotopes have been characterized; the most stable are 60 Co with a half-life of … WebProtons and Neutrons in Magnesium. Magnesium is a chemical element with atomic number 12 which means there are 12 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10 …

Strontium-89 was first synthesized in 1937 by D. W. Stewart et al. at the University of Michigan; it was synthesized via irradiation of stable strontium (88 Sr) with deuterons. Biological properties and applications of strontium-89 were studied for the first time by Belgian scientist Charles Pecher. Pecher filed a patent in May 1941 for the synthesis of …

Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. There are nuclides that are unstable and radioactive.
WebAnd so the symbol that we'll draw here for protium is going to have the element symbol, which is, of course, hydrogen, and then down here we're going to write the atomic number. So the subscript is the atomic number which is one, because there's one proton in the nucleus, and then for the superscript, we're going to write in the mass number.
