This is an especially complicated valency problem, because Fe3O4 is a combination of Fe2O3 and FeO. As usual, except in peroxides and superoxides, oxygen is assigned a valency of -2. This means that the iron in Fe2O3 has a valency of +3 while the iron in FeO has a valency of +2. (Note that these two oxides of iron also occur separately from each other, as well as in Fe3O4.) Therefore, the average valency of iron in Fe3O4 is 8/3, a rare example of fractional valency made possible only by the fact that iron in this compound actually exists in two integral valence states in the same compound.

How do you calculate the percentage composition of calcium sulfate?
You find the weights of each element in the compound and divide by their relative atomic mass to find out the moles. You find the simplest ratio of the mole values you have found and then you can find the percentages using this ratio
How do you know when to solve for a empirical formula?
If it tells you to find the empirical formula when percent composition is given or if the mass of each element is given in a specific compound.
What are the characteristics of an element?
There are both physical characteristics and chemical characteristics associated with each of the one hundred and some odd known elements. Each question is covered separately, and you'll find them linked below.To discover the characteristics of a given element, use the search window above to see what is posted for that element.-- Answers4Lyf added:An element is a substance made up of only one type of atom. It cannot be simplified any further; you can't split up an element. See periodictable.com for the elements discovered.
How many electron rings does the element Phosphorus have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
What are some common items that consist of only one element?
If something is made of only one element, then it is an element. I do not believe that you will find an everyday item that is a pure element! :)
How do you find valency?
The valency of an element measures its ability to combine with other elements. This valency is determined by the number of electrons in the outer shell of each atom of an element.
How do you find out valency of manganese?
Manganese is a transition element and has a variable valency but generally has a valency of 2 and exists as Mn2+
How do you find the valance of an element in the periodic table?
the group number represents the valency of the elements.
How do you find valency of elements?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
How calculate valency?
Valency is calculated in this way... 1. Find atm no of that element. 2. Write down electronic configuration. 3. Take the valence shell electron number. 4. The number of electrons to be lost are added as the valency.
How do you find valency of an element?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
How do you find covalence of nitrogen in dinitrogen pentoxide?
according to old concept of valency ,valency of an element= 2xno. of oxygen atoms.here 1atom of N combines with 5/2 atom of O.thus covalency of N is 5
How do you find the chemical formula of sodium oxide?
Well you should know the formula and valency of each element first, Sodium formula - Na valency - +1 Oxide formula - Oxygen - O valency - (-2) Since the charge of the compound has to be 0 (zero) 2 atoms of sodium (+2) are required to neutralize the effect of the one oxygen atom (-2) ----------- [2 + (-2) = 0] Na2O
How to find valency of PO4?
PO4^-3 is an ion.So its valency is -3
How do you take out valency an element?
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
What is the valency of trioxosulphate IV?
it is the stupidest compound whos valency is really difficult to find
How do you find the valency of radicals?
Mercury
