The shell effect and isospin effect in nuclear charge radii are systematically investigated, and a four-parameter
formula is proposed for the description of the root-mean-square (rms) charge radii by combining the shell
corrections and deformations of nuclei obtained from the Weizs¨acker-Skyrme mass model. The rms deviation
with respect to the 885 measured charge radii falls to 0.022 fm. The proposed formula is also applied for the
study of the charge radii of superheavy nuclei and nuclear symmetry energy. The linear relationship between the
slope parameter L of the nuclear symmetry energy and the rms charge radius difference of the 30S-30Si mirror
pair is clearly observed. The estimated slope parameter is about L = 54 ± 19 MeV from the coefficient of the
isospin term in the proposed charge radius formula.
