Can anyone explain a and b? i know that, for c, electrons get shared so that the compound becomes neutral (example a +2 atom will bond with a -2 atom, and a -4 atom will bond with two +2 atoms,

iron is a transition metal and, as such, can form two types of "oxide" compounds, feo and fe₂o₃.

(a) what's different about the iron cations in each compound?

(b) how does that difference affect the final compound formulas?

(c) explain what happens to the electrons when iron and oxygen atoms combine to form either of these compounds.
