Na+ sodium ion has 11 protons, 12 neutrons and 10 electrons
20 protons and 18 electrons
23 electrons, 26 protons, 30 neutrons.
P3- has 15 protons, 16 neutrons and 18 electrons.
13 protons and 14 neutrons. The fact that its an ion doesn't change that ... only the number of electrons.

electrons have negligible mass. the mass of the ion depends on how many protons and neutrons are present.
The ion Ce(3+) of the isotope Ce-140 has 58 protons, 82 neutrons and 55 electrons.
P3- has 15 protons, 16 neutrons and 18 electrons.
29 protons and 27electrons are present in Cu2+ ion.
13 protons and 14 neutrons. The fact that its an ion doesn't change that ... only the number of electrons.
Te2- ion
16 protons, and if it isn't an ion ("isn't an ion" means that it has no electric charge), it has 16 electrons. on average, sulfur has 16.065 neutrons, but that's averaged out, so it's a weird number. let's just say most sulfur has 16 neutrons.
Mg has 12 protons, 12 electrons and 12 neutrons.Mg^2+ ion has 12 protons, 10 electrons and 12 neutrons. The number of protons and neutrons remains the same, but since the ion now has a 2+ charge, it has lost 2 electrons.
