How do i list the numbers and types of atoms represented by chemical formulas.
Example Fe2O3

The subscipts tell you the number of atoms. For example, in Fe2O3 there are two atoms of Fe and three atoms of O. I don't understand the part about types. Please clarify if this doesn't answer completely. You may mean that Fe is a metal and O is a non-metal.
