The short answer is the the charge of the steel atom in FeO is +2, due to the fact that it requirements to balance the -2 fee of the oxygen atom to create a neutral FeO molecule.

Iron is an amazing metal because it have the right to have various oxidation states (aka fees in a molecule). A an excellent way to discover this is come look in ~ the different iron oxide compounds that can exist. There is FeO (where Fe is +2 and O is -2), i m sorry is also called wüstite. over there is Fe2O3 (where each Fe is +3 and each O is -2). That is also possible for iron to form a mixed oxide (which has Fe in both the +2 and also +3 states), such as Fe3O4. What room the oxidation says (charges) of every Fe atom in the Fe3O4 molecule? Remember, in a blended oxide, the fees on Fe aren"t every the same!

Many atoms nearly always take the exact same oxidation state. Iron just doesn"t. The factor for this, simply put, is that iron"s ar in the routine table puts it in a team of elements called transition metals.

change metals deserve to take oxidation states varying from +1 to +4, though most generally they take +1 and +2. The valence electrons of change metals (which space the electrons they "lose" once they bond v an atom like oxygen) are very close in energy, meaning that the atom feels only a little energy change--relative to the energy readjust of bonding--when it loser 1 versus 2 versus 3 electrons. This is what makes iron tricky, but it additionally makes it a versatile material that we encounter in many forms in nature.

Answer 2:

When us say "charge" in one atom, we usage a number the determines the electromagnetic interactions of the atom. In stole (II) oxide, or Ferrous Oxide, or FeO, the Iron facet (Fe) is bonded to the Oxygen, in the oxidation state that "2". This method that the stole has accepted 2 electron from the Oxygen. because of this electromagnetic interaction, the fee of the steel (Fe) in FeO is 2+.

Remember the oxidation defines the ns of one electron by a molecule or atom. In FeO, you have one atom that Fe with 2 extra protons (+charge), and also the Oxygen is an atom through two extra electron (-charge). Both atoms will lure to every other because of their an essential force that nature, the electromagnetic interaction.
