What is the oxidation state of chromium in CrO?
Hi, CrO5 is a compound which has the structure which has peroxide linkage(O2 2-) as shown: Thus the oxidation number of Chromium can be calculated as : Let the oxidation number of Cr be x, then x-2-2(2)=0 x-2-4=0 x-6=0 thus x=+6
How do you figure out the formula for chromium 4 oxide?
Balance the oxidation states on the atoms in the molecule. An oxide always contains oxygen in -2 oxidation state , in ionic compounds this is O2-. As the chromium is Cr(IV) in +4 oxidation state, ( shown as an ion Cr4+ ) you can balance the states or charges which ever way to get CrO2 (which you can write as Cr4+ (O2-)2 )
What is the oxidation charge of chromium?
Usually +2, but all the different charges (+3, +6) can be found in chromium's box on the table.
Is Cr a transition metal?
Yes, chromium is a transition state metal.
What is full form of cr?
Chromium. (Cr)
What is the oxidation state of chromium in CrO?

What is the oxidation number of Cr in CrBr?
In CrBr (chromium monobromide) Cr would have an oxidation number of +1. This compound is not known perhaps you meant CrBr3, where chromium has an oxidation number of +3
What is the oxidation number of Cr2O72?
In Cr2O72- chromium (Cr) has an oxidation number of 6+ while oxygen has an oxidation number of 2-.
What is oxidation number of chromium in Cr2O7?
The oxidation number of chromium in Cr2O7 is +7. The oxidation number of oxygen is -2, so 7 O atoms times -2 = -14. In order to balance the -14 on the oxygen atom, each chromium atom must have an oxidation number of +7, because 2 Cr atoms times +7 equals +14.
What is the oxidation state of chromium in the compound K2Cr2O7?
In this kind of compound, oxygen is conventionally assigned an oxidation number of -2 and potassium an oxidation number of +1. For electrical neutrality, chromium must have an oxidation number of + 6, because 2(+1) + 2(+6) + 7(-2) is zero.
What is the oxidation number for Cr in Cr2O3?
+6 for Cr, -2 for each O in Cr2O72-oxidation number for oxygen is -2 so 7 of them makes -14 in total but the compound has an overall charge of 2- so therefore +12 is required. As there are two chromium then the oxidation number for each one is +6
What is the chemical formula of chromium 3 nitrate?
CrNO3 ************2nd Opinion*********** To get the correct formula, you need to state the oxidation number of chromium in the compound, using a Roman numeral. It's likely to be chromium(III) nitrate, which is Cr(NO3)3
What is the formula for chromium iii iodide?
Chromium has four oxidation states: 2, 3, 4, and 6.Iodine has one, and it's -1.There will be a iodide for each oxidation state of chromium.CrI2 Chromium (II) iodideCrI3 Chromium (III) iodideCrI4 Chromium (IV) iodideCrI6 Chromium (VI) iodide
Oxidation number of Cr in K2Cr2O7?
Potassium is the metal here and it has an Oxidation number of +1 in every compound because all Alkali Earth metals have an Oxidation Number of +1. (The other elements: Oxygen -2 and Chromium (Cr) +6)
What is the oxidation number of chromium in potassium dichromate?
potassium dichromate is K2Cr2O7. The oxidation number of Cr is -6. (Oxygen is -2, K is +1 so Cr must be -6)
What is the the oxidation number of chromium in Cr2(SO4)3?
Well, without being given an equation, we presume you mean the o.n. of chromium. H in this is +1, so H+H=+2 4 x O= -2 x 4 = -8, therefore Cr = +6 as the whole element has to equal zero. and i do believe in this form it normally goes to Cr +3
What is the formula for chromium III bromide hexahydrate?
Chromium has four oxidation states: 2, 3, 4, and 6. Chlorine has one, and it's -1. There will be a chloride for each oxidation state of chromium. Here they are: CrCl2 Chromium (II) chloride CrCl3 Chromium (III) chloride CrCl4 Chromium (IV) chloride CrCl6 Chromium (VI) chloride
