Abstract: The nuclear mass(or binding energy) and charge radius are fundamental physical quantities of an atomic nucleus, which can provide important information for nuclear physics and astrophysics. This paper discusses the systematics of nuclear mass and its related physical quantities(such as neutron-proton interaction, pairing interaction, separation energy, α-decay energy and Coulomb energy), as well as nuclear charge radius and so on. These systematics are not only practical methods for predicting unknown physical quantities such as nuclear masses and charge radii with high precision, but also provide effective constraints on the coefficients of nuclear symmetry energy and Wigner energy, and give a simple way to study the evolution of collective motion of low-lying states of nuclei. As a Supplemental Material of this paper(see Science Data Bank), a TABLE including predicted physical quantities such as atomic mass excesses(or binding energies) and nuclear charge radii is provided.
