The primordial nucleosynthesis of intermediate-mass nuclei up to A = 28 in the neutron-rich and proton-rich environments produced by baryon-number-inhomogeneous big bang models is discussed. It is found that there could be several observational signatures of such neutron-rich and proton-rich primordial nucleosynthesis if sufficiently accurate isotopic and elemental abundance ratios could be measured for extremely metal-poor stars. These observations could also provide important information about the degree of baryon-number inhomogeneity at the time of primordial nucleosynthesis.
