A novel and unique model based on the singlet state of (proton–neutron) pair as a building block is postulated for nucleosynthesis of different nuclei. The presently accepted alpha cluster model is inadequate for the explanation of the formation of 7Li, 8Be, 10B, their stability and abundance. Problem of Beryllium bottleneck and the explanation of Hoyle’s state of 12C appear to be insurmountable by the cluster model. Proton and neutron combine to form deuteron (spin 1) and another species (isomeric with deuteron, with spin 0) obeying Pauli Exclusion Principle and is termed Paulion. The corresponding element is Christianized as Paulium (Pl), hitherto unrecognized isomer of hydrogen. The newly identified species, is capable of formation of alpha particle following Bose-Einstein Statistics. The Paulion condensation model is applied to build-up different isotopes of Li, Be, B, C, N and O and can resolve the existing puzzle in the nucleosynthsis of stable 12C. It can explain the abundance and the properties of different nuclei. An empirical equation A = Z (p – n) pair + (A - 2Z) n explains the composition of different nuclei where A is the mass of the nucleus, Z being its number of proton.
