N2 - seven RMF parameter sets to study the effects of coupling isovector-isoscalar, tensors, and electromagnetic exchange on prediction of proton driplines. To determine the position of one and two proton driplines of the chain of N = 28 isotones, we use separation energies and single particle energy methods. Our calculation results have shown that prediction two proton dripline of N = 28 isotones using separation energy lies at Z = 30 for 0.04+T-E and 0.055+T-E parameter sets and it lies at Z = 32 for the one of other used parameter sets and the one from experiment. While based on single particle energy and the proton Fermi energy analysis, the proton dripline lies at Z = 30. We also obtain by using one proton separation energy, the dripline lies at Z = 29 for 0.04+T-E and 0.055+T-E parameter sets and for the one of other used parameter sets and one from experiment lies at Z = 31 . While based on the single particle energy and proton Fermi energy analysis, it lies at Z = 31. We obtain that coupling isovector-isoscalar, tensors, and electromagnetic exchange couplings do not provide a significant effects on the prediction proton driplines. We also observe that one and two proton driplines do not have a strong correlation with bulk properties nuclei, such as skin, binding energy, and so on.
