Since the definition of the p-nuclei depends on the current knowledge of the s- and r-process (see also nucleosynthesis), the original list of 35 p-nuclei may be modified over the years, as indicated in the Table below. For example, it is recognized today that the abundances of Gd and Er contain at least strong contributions from the s-process. This also seems to apply to those of In and Sn, which additionally could be made in the r-process in small amounts.
