Decay Rate/Half-life of Radioisotopes (Illustrations).Carbon-14: with 6 protons and 8 neutrons and an atomic mass of 14.Carbon-12: with 6 protons and 6 neutrons and an atomic mass of 12.Two different forms, or isotopes, of carbon are shown below:.The number of neutrons in the nucleus is equal to A minus Z."A" is usually placed to the left above the element symbol.
The atomic mass of the element (number of protons plus the number neutrons) is represented by "A". All the isotopes of an element have the same "Z". The number of protons in the nucleus is represented by "Z", the atomic number. The illustration below shows the chemical symbol for the hypothetical element "X".
