The ions Cr3 plus and O2- combine to form the ionic compound chromium oxide. In what proportions do these ions combine to produce a neutral compound?
The Cr3+ ion has a +3 charge, while the O2- ion has a -2 charge. To form a neutral compound, we need two O2- ions to balance the charge of one Cr3+ ion. Therefore, the ions combine in a 1:2 ratio to produce the ionic compound chromium oxide (Cr2O3).
What is the Oxidation number of cr plus 3?
The oxidation number of Cr in Cr3+ is +3. This is because each Cl ion has a charge of -1, and since the compound is neutral, the total positive charge from Cr must equal the total negative charge from the Cl ions.
What is the equation for a chromiumIII ion from a neutral chromium atom?
A chromium atom loses three electrons to become a Cr3+ ion. The equation for this process is Cr → Cr3+ + 3e-.
What transition metal has 24 electrons and plus 3 ions?
The transition metal with 24 electrons is chromium (Cr) and its common ion with a +3 charge is Cr3+.
How many electrons does the neutral atom gain or lose when Cr3 plus forms?
When Cr3+ forms, the neutral atom (chromium) loses 3 electrons. This happens because the neutral chromium atom has 24 electrons, but when it forms Cr3+, it loses 3 electrons to have a total of 21 electrons.
Is Cr3 plus plus e-Cr2 plus reduced or oxidised?
In the ion-electronic chemical equation Cr+3 + e-1 => Cr+2, the Cr+3 ion is reduced.

What is the charge for a chromic ion?
A chromic ion, Cr3+, has a charge of +3 due to the loss of three electrons from a neutral chromium atom.
What is the formulae of the compound formed by Cr3 plus f minus1?
The compound formed by Cr3+ and F- is chromium(III) fluoride. The chemical formula is CrF3.
Will Cr3 plus have a noble gas configuration?
Yes, Cr3+ will have a noble gas configuration. It will have the electron configuration of argon (Ar) due to the loss of three electrons from the chromium atom.
