In Fe atoms, the 3d orbitals are partially filled. Iron (Fe) has an electron configuration of [Ar] 3d^6 4s^2, where the 3d orbitals contain 6 electrons.
fe+3=..............* .9 =fe+2
To balance the equation Al + Fe3N2 -> AlN + Fe, you need to make sure that the number of each type of atom is the same on both sides of the equation. First, balance the Al by putting a coefficient of 2 in front of AlN to match the 2 Al atoms in Fe3N2. Next, balance the Fe by putting a 3 in front of Fe on the product side to match the 3 Fe atoms in Fe3N2. The balanced equation is: 2Al + 3Fe3N2 -> 2AlN + 9Fe.
2 atoms
There are 6 atoms in the compound H2C2O2: 2 hydrogen (H) atoms, 2 carbon (C) atoms, and 2 oxygen (O) atoms.

There are 4 atoms in Fe2O2: 2 atoms of iron (Fe) and 2 atoms of oxygen (O).
There are 10 atoms in Fe2O4 - 2 iron (Fe) atoms and 8 oxygen (O) atoms.
Two atoms in 2 atoms of Fe (this dose not make sense pleas edit)
In 2Fe2O3, there are 2 iron (Fe) atoms and 3 oxygen (O) atoms, giving a total of 5 atoms.
In Fe2O3, there are 2 iron (Fe) atoms and 3 oxygen (O) atoms, totaling 5 atoms in one molecule of Fe2O3.
There are 6 atoms of oxygen represented by this.
There are two Fe atoms and three O atoms, making a total of five atoms altogether.
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
One molecule of iron oxide (Fe₂O₃) contains two iron atoms.
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.
There are 4 elements in FeCl3: iron (Fe) and three chlorine atoms (Cl).
