The nuclear charge is the total charge in the nucleus for all the protons. It has the same value as the number of atoms. As we move through the periodic table by through the atomic load. When you reach the end of a cycle and go to the start of the next period, the number of atoms and the nuclear charge continues to rise.
The term effective nuclear charge should be used in place of nuclear charge. Effective nuclear charge takes into account the behavior of all electrons whether they constitute the valence shell that is present in the inner shells.
Consequently, the nuclear charge is not subject to periodic or repeated existence. The nuclear charge is only continuing to increase. Whether you’re going through the time or down a band, this is real. The nuclear charge is the total charge in the nucleus for all the protons. It has the same value as the number of atoms. Going through the periodic table, the nuclear charge increases.
