Web3 okt. 2013 · It is always composed of the same three elements: carbon, hydrogen, and oxygen. Moreover, the elements that make up any given compound always occur in the same relative amounts. In glucose, there are always six carbon and six oxygen units for every twelve hydrogen units. But what, exactly, are these “units” of elements? WebIsotopes have the same atomic number Z as the nuclide, but different numbers of neutrons and hence atomic mass A: (2.2) Nuclides may be stable or unstable. Radionuclides are nuclides that possess properties of spontaneous disintegration. About 1700 nuclides are known, of which about 300 are stable and the rest radioactive.
