I^- is the most common ion of Iodine.
The most common Selenium ion is Se2- the selenide ion. It is in the same group as oxygen and its most common ion in the oxide ion O2-.
A chromium ion is not neutral. By definition an ion is not neutral. All atoms belong to an isotope, but that has nothing to do with whether the atom is ionized or not.

Cadmium has a divalent cation: Cd2+.
they all have the same element with the same number
Cadmium is a divalent metal with the cation Cd+.
N-14 is the most common isotope of nitrogen atom and it has 7 protons, 7 neutrons
Cadmium forms ion with +2 charge. It is Cd2+
I^- is the most common ion of Iodine.
The most common Selenium ion is Se2- the selenide ion. It is in the same group as oxygen and its most common ion in the oxide ion O2-.
The most common isotope of chromium is Cr-52. To determine the most common isotope of any element, look at the periodic table and find the element in question. Chromium is number 24, Cr. The atomic mass is 51.996 amu. That's the average atomic mass. The most common isotope has the mass of the nearest whole number to 51.996. The most common isotope of chromium would then be Cr-52, with a mass of 52. Cr has 24 protons, and 24 electrons. Cr-52 would have 52-24= 28 neutrons.
P3- is the most common ion of phosphor. Howver, when combined with other elements such as oxygen, the phosphate ion PO43- is the most common.
The fluorine isotope differs from the fluorine ion because the fluorine isotope has a different number of neutrons from normal, while the ion has a different number of electrons. An isotope will have the same number of electrons as its atomic number (the number of protons), while the ion will add (more common in the case of fluorine) or subtract (very rare in the case of fluorine) electrons to the atom. The only thing they are similar in is the number of protons they have, which are the same.

It is an isotope of a neutral atom.
