WebFeb 13, 2014 · Mass of 10 000 atoms of Cl = 354 500 u Average mass of a Cl atom = (354 500 u)/ (10 000 atoms) = 35.45 u The more abundant an isotope, the closer the atomic mass will be to the atomic mass of that isotope. Since Cl-35 is more abundant, the average atomic mass will be closer to 35 than to 37. Answer link
Web19K) has 26 known isotopes from 31 K to 57 K, with the exception of still-unknown 32 K, as well as an unconfirmed report of 59 K. [3] Three of those isotopes occur naturally: the two stable forms 39 K (93.3%) and 41 K (6.7%), and a very long-lived radioisotope 40 K (0.012%) Naturally occurring radioactive 40 WebSo A is the mass number, which is equal to the number of protons, that's the atomic number which we symbolized by Z, plus the number of neutrons. So A is equal to Z plus N. And for protium, let's look at protium here. So in the nucleus there's only one proton and zero neutrons, so one plus zero gives us a mass number of one.
WebElements have families as well, known as isotopes. Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table. For example, carbon has six protons and is atomic number 6. WebNevertheless, measuring isotopes is important (mass spec), and can offer clues about what might have happened. For example, the oxygen isotope ratios in an ancient seashell …
