The unstable elements that are significantly different from being isotropic merit recognition for their atypical properties. They have extreme neutron-to-proton ratios, distinct outer elects distributions, meager binding intensities, and are likely to form nuclear halos and change their nuclear shapes. While they are transient, investigating these elements is crucial in the context of the swift neutron capture – r-process in the evolution of the chemical elements. Contrary to their stable isotopes, these unstable isotopes can undergo swift nuclear reactions, which narrows the knowledge gap in astrophysical processes. The insights gained on cosmic evolution through these investigations could help in comprehending natural events and the origin of life. Similarly, the distorted nuclei configuration, uncommon reaction styles to their varying stability status, and the meager binding energies make them critical in elucidating complex decomposition paths as well as reaction mechanisms. Subsequently, exploring hypothetical scenarios in the evolution of cosmic chemistry is possible through their unconventional characteristics.
