  Starting from light to superheavy nuclei, we have calculated the effective
surface properties such as the symmetry energy, neutron pressure, and symmetry
energy curvature using the coherent density fluctuation model. The isotopic
chains of O, Ca, Ni, Zr, Sn, Pb, and Z = 120 are considered in the present
analysis, which cover nuclei over the whole nuclear chart. The matter density
distributions of these nuclei along with the ground state bulk properties are
calculated within the spherically symmetric effective field theory motivated
relativistic mean field model by using the recently developed IOPB-I,
FSUGarnet, and G3 parameter sets. The calculated results are compared with the
predictions of the widely used NL3 parameter set and found in good agreement.
We observe a few signatures of shell and/or sub-shell structure in the isotopic
chains of nuclei. The present investigations are quite relevant for the
synthesis of exotic nuclei with high isospin asymmetry including superheavy and
also to constrain an equation of state of nuclear matter.
