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.
cr-52 and cr-53
3+ or 2+
it is a chromium 2 as a good point of reference, and if you don't know the specific charge of an atom, check the ion to which it is bound: the phosphide ion is most commonly charged as a 3- ion because its period is has 3 electrons more than it needs to form a complete octet 2 phosphide ions (per your empirical formula) would have a total ionic charge of 6- if you distribute the (6-) charge evenly through the 3 chromium ions in your empirical formula, then each chromium ion would have to have a charge of 2+ in order for the ionic salt to be neutrally charged. therefore the chromium is chromium (II)
The most common charge of phosphorus is -5.
The oxygen ion has a coomon charge of '2-'.
The chromic ion is the chromium (III) ion.
The chlorine atom typically becomes an ion with a charge of minus one.
-2 is the most common charge (sulphide ion).
The most important cation of chromium is Cr3+; but also exist Cr3+, Cr6+, Cr1+, Cr4+, Cr5+.
A Magnesium ion has a charge of 2+.

The most common charge of phosphorus is -5.
The oxygen ion has a coomon charge of '2-'.
Ba has no charge overall but the Barium ion has a 2+ charge.
The chromic ion is the chromium (III) ion.
CrCl3: A chloride ion has only a single negative charge; therefore, three of them are required to have the same magnitude of electric charge as a chromium (III) ion.
The most common ion formed from a single sulfur atom is a sulfide ion, with a charge of -2.
The chlorine atom typically becomes an ion with a charge of minus one.
2-. O2- is the oxide anion
