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.
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 are the cations in the compound CrOH3?

Cr3+ ions
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.
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.
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 chemical formula for chromium II Phosphate?
Cr+2 P-3 ----> these are the ions and their charges. You know chromium's charge because of the roman numeralCr+2 Cr+2 Cr+2 P-3 P-3 ------> the charges have to add up to zero, so three +2 Cr ions plus two -3 P ions cancel each other outCr3P2 -----> simplify
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 most common ion for chromium?
The most important cation of chromium is Cr3+; but also exist Cr3+, Cr6+, Cr1+, Cr4+, Cr5+.
What are the differences between cr2 and cr3 file formats?
The main difference between CR2 and CR3 file formats is that CR2 is the older version used by Canon cameras, while CR3 is the newer version that offers improved compression and image quality. Additionally, CR3 files may contain more advanced features and metadata compared to CR2 files.
