Two atoms in 2 atoms of Fe
(this dose not make sense pleas edit)
Two atoms
Two.
1
2 atoms
fe+3=..............* .9 =fe+2
2 Sulfur atoms and 3 Oxygen atoms
One! You may mean to ask how many atoms there are in one molecule of oxygen, in which case the answer is two.
Formula = Fe(ClO4)2Formula: Fe(ClO4)2

There are 6 atoms of oxygen represented by this.
Molar mass of Fe(NO3)2 is 55.85 + 2(14.00 + 3(16.00)) = 179.85 g/mol Therefore, number of moles of Fe(NO3)2 present is 53.55/179.85 = 0.2977 mol For each molecule of Fe(NO3)2, there are two atoms of nitrogen associated with it. Therefore, there are 0.2977*2 = 0.5954 mol of nitrogen atoms
There are two Fe atoms and three O atoms, making a total of five atoms altogether.
Iron(II) tungstate, FeWO4, is an ionic compound which means that the smallest particle is a formula unit. One formula unit of FeWO4 has one Fe^2+ ion.
Ferric sulfide has 2 Fe (iron) atoms and 3 S(sulfur) atoms. So totally 5 atoms.
2 Magnesium OR Iron atoms to 1 Silicon, 4 Oxygen atoms. A formula of (Mg, Fe)2 Si O4
Well, iron oxide is a combination of iron(Fe) and oxygen (O). We know Fe(III) has a charge of +3 and oxygen has a charge of -2, so we must balance them. Their LCF is 6, so to balance them, we must have 2 atoms of iron (3x2=6) and 3 atoms of oxygen (-2x3=-6). Therefore we know that there are 2+3 atoms in this molecule, so 6 atoms in the molecule.

If iron(II), then iron sulfate is FeSO4. This has a single Fe atom per molecule (or two Fe in two molecules). If you have iron(III), then iron sulfate is Fe2(SO4)3. This compound has two iron atoms per molecule (or four Fe in two molecules).
ferrous (iron atoms) give electrons to chlorine atoms 2 Fe(s) + 3 Cl2(g) → 2 FeCl3(s)
