T here are four principle orbitals (s, p, d, and f) which are filled according to the energy level and valence electrons of the element. All four orbitals can hold different number of electrons. The s-orbital can hold 2 electrons, and the other three orbitals can hold up to 6, 10, and 14 electrons, respectively.

TīmeklisThe only thing I know how to do is calculate the electron configurations of each element. For Iron, it is $1s^22s^22p^63s^23p^64s^23d^6$. For Oxygen, it is $1s^22s^22p^4$. I am told that based on the electron configuration you can get the valence of each element. And then, you can calculate the valence of $\ce {FeO}$ and $\ce {Fe_2O_3}$. In chemistry, iron(II) refers to the element iron in its +2 oxidation state. In ionic compounds (salts), such an atom may occur as a separate cation (positive ion) denoted by Fe . The adjective ferrous or the prefix ferro- is often used to specify such compounds — as in "ferrous chloride" for iron(II) chloride, … Skatīt vairāk All known forms of life require iron. Many proteins in living beings contain bound iron ions; those are an important subclass of the metalloproteins.
