The charge of the electron is about -1.60217733 x 10-19 C, the charge of the proton is equal and opposite to that of the electron, both charges are constant.
Introduction: The effective nuclear charge is the pull that the specific electron feels from the nucleus. Example; hydrogen atom contains one proton and one electron. The effective nuclear charge on electron is equal 1 in hydrogen atom. Helium contains two protons and two electrons. But there is not the effective nuclear charge equal 2 on each electron in helium atom, it is about 1.7 units. There is some rules for calculation the effective nuclear charge in modern physics. But there are not analyses about it.
