The effective nuclear charge refers to the protons/nucleus of an atom, not the electrons. In terms of periodic trends, the effective nuclear charge increases as you go across a period because the atomic number increases and electrons are being added to the same energy level. It decreases down a group because the atomic radius, number of energy levels, and number of electrons increases, leading to the shielding effect and electron-electron repulsion.
