No, the nuclear charge of an atom and the nuclear charge of an ion are equal
Explanation:
The nuclear charge of an atom is the sum of the charges in the nucleus of the atom and since the positively charged protons are the only charged particle in the nucleus of an atom, we have that the number of protons is equivalent to the nuclear charge of an atom
However, since the charge of an ion is gained only by the loss or gain of electrons in its valence shell, we have that the nuclear charge of the nucleus remains unchanged and equal to the nuclear charge of the atom.
