What is the oxidation state of copper in the compound CuCl2?

+2 oxidation state for the Copper. -1 for the Chloride


In the compound Ni2O3 nickel's oxidation number is and oxygen's oxidation number is -2?

In the compound Co2O3 cobalt has an oxidation number of 3 while oxygen has an oxidation number is -2.


In the compound Fe2O3 irons oxidation number is while oxygens oxidation number is 2?

The oxidation number of iron in this compound is 3. The oxidation numbers of the total oxygen atoms and the total iron atoms must be the same in a neutral compound. There are three oxygen atoms, giving a total for oxygen of 3 X 2 = 6. There are only two iron atoms; therefore, each one must have an oxidation number of 6/2 = 3.


What is the oxidation number for BaF2?

The compound has no charge. This means that the positive oxidation numbers must equal the negative oxidation numbers. 'H' always has an oxidation number of +1. There are three of these atoms in the compound giving +3. To cancel out this positive number, the 'B' must equal -3.


What is the sum of all oxidation numbers in any compound?

The oxidation number of oxygen in most compounds is -2.


The sum of oxidation numbers in a neutral compound is always?

The sum of oxidation numbers in a neutral compound is always zero. (Note that in order for this to be true, the oxidation number of each type of atom present must by multiplied by the number of such atoms present in the formula unit for the compound before the addition is performed.)


What is the least number of atoms in a compound?

A compound must have at least two atoms of different elements.


Name given to elements with more than one oxidation number?

The following elements have more than one oxidation number: Mercury, Chromium, Copper, Iron, Tin, and Lead. The ones with different oxidation numbers, also has a sort of name that goes with it. For example, Pb+4's name is actually "Plumbic".


In the compound Al2O3 aluminum has an oxidation number of 3 while oxygen's oxidation number is .?

In the compound Al2O3, aluminium has an oxidation number of +3, while oxygen's oxidation number is __-2 ____. For aluminium oxide (Al2O3) to form the ionic charges MUST balance. Hence For the 2 aluminiums it is 2 x 3 = +6 For the 3 oxygens it is 3 X -2 = -6 +6 -6 = 0 So the charges balance, hence Al2O3 is neutrally charged compound and NOT an ion.


The formula for a compound is represented x2y the oxidation number of y is 2 what is the oxidation number for x?

A molecule of a compound must be electrically neutral overall. There is only one y atom in the formula, so that the total contribution of charge from y is +2. There are two x atoms, and each of them must have an oxidation number of -1 for a total of -2 to neutralize the charge from y.
