The nuclei lying in the vicinity of the proton drip line are proton emitters. A systematic analysis of the half-life of one proton emitter was estimated using the Effective Liquid Drop Model. We have exploited various mass tables say AME2020, WS4+RBF, FRDM, and KTUY in evaluating the Q-values. The half-lives obtained using various mass tables are compared with experimental values. Among the theoretical mass tables, WS4 is found to have less deviation in the prediction of the half-lives of one proton emission. Alpha-decay half-lives are also estimated to determine which decay mode dominates in the selected isotopes. Geiger–Nutall plots have been plotted and the linear nature of the graph has been successfully reproduced for all the mass tables. The New Geiger–Nuttal law, which illustrates the angular momentum dependency on half-life, also reproduces the linear nature of the graph.
