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. WebAnswer (1 of 5): Initially, when the first standards were set, the calculation of molecular mass was indeed based on the Hydrogen-1 element. But, later the norms and standards were shift to the Carbon C-12 isotope. The reason is pretty simple and logical. The mass of the Hydrogen-1 element is ab... closed packed position enkel

Some isotopes/nuclides are radioactive, and are therefore referred to as radioisotopes or radionuclides, whereas others have never been observed to decay radioactively and are referred to as stable isotopes or stable nuclides. For example, C is a radioactive form of carbon, whereas C and C are stable isotopes. There are about 339 naturally occurring nuclides on Earth, of which 286 are primordial nuclides, meaning that they have existed since the Solar System's formation.
