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.

To determine the types of atoms represented by chemical formulas, you need to understand the symbols used for each element. In the chemical formula Fe2O3, "Fe" represents iron and "O" represents oxygen. Iron is a transition metal, while oxygen is a non-metal.

To count the number of atoms, you need to look at the subscripts following each element symbol. In Fe2O3, the subscript "2" indicates that there are two atoms of iron (Fe), and the subscript "3" indicates that there are three atoms of oxygen (O).

By analyzing the chemical formula, you can determine both the number and types of atoms present. In the example Fe2O3, there are two atoms of the metal iron (Fe) and three atoms of the non-metal oxygen (O).
