We demonstrate the different effects of different baryon impurities on the static properties of nuclei within the framework of the relativistic mean-field model. Systematic calculations show that \ensuremathΛc+ and \ensuremathΛb have the same attracting role as the \ensuremathΛ hyperon does in lighter hypernuclei. \ensuremathΞ^\ensuremath- and \ensuremathΞc0 hyperons have the attracting role only for the proton distribution and have a repulsive role for the neutron distribution. On the contrary, \ensuremathΞ0 and \ensuremathΞc+ hyperons attract surrounding neutrons and reveal a repulsive force to the protons. We find that the different effects of different baryon impurities on the nuclear core are due to the different third components of their isospin.
