WebFrom lithium to fluorine, those electrons are all in the 2-level, being screened by the 1s 2 electrons. The increasing number of protons in the nucleus as you go across the period pulls the electrons in more tightly. The amount of screening is constant for all of these elements. In the period from sodium to chlorine, the same thing happens. WebSince the overall charge is 0, the positive and negative charges from the irons and oxygens have to sum up to 0. The least common multiple between 2 and 3 is 6 so we have to multiply the +3 by 2 to get +6, and the -2 by 3 to -6. This means we need 2 iron atom, and 3 oxygen atoms, or Fe2O3. Hope that helps. 2 comments.
