Name: Iron (III) oxide
Should this be separated just like this for the first step?
Type 1 Ionic compounds : Non transition metal cation + Non metal anion. Name of cation + Name of anion in "ide" form. Type 2 Ionic compounds : Transition metal cation + Non metal anion. * Name of cation + ("its charge in roman numerals") + Name of anion in "ide" form. Ionic compounds with polyatomic ions : * Same as above, just replace the name of the anion in "ide" form with the name of the polyatomic ion. Molecular compounds : Both non metal, share a pair of electrons. * Prefix + Name of the first element + Prefix + Name of the second element in "ide" form. ! All of the acids' formulae start with Hydrogen. Binary acids : Compounds in which Hydrogen is combined with a non-metal anion. "Hydro" + Base name of the non-metal + "ic" + "acid". Oxyacids : Acids made from Hydrogen, Oxygen and at least another element. Hydrogen + polyatomic anion containing Oxygen. * If the oxoanion's name ends with "ate" : Base name of the oxoanion + "ic" + "acid". * If the oxoanion's name ends with "ite" : Base name of the oxoanion + "ous" + "acid". Hydrates : Compounds that have a specific number of water molecules attached to them. Name of the compound + Prefix + "hydrate". If water is removed : "Anhydrous" + Name of the compound.
It fitted my needs, it was a one semester course as a non chemistry student, like a general requirement.That list is not complete. Different ions or different oxidation states of the same element have slightly different names.
Try get fixed in mind quickly. Nomenclature is essent in chemistry, but needs to become second nature as pretty boring as a subject in itself.
Great. So tell me how you determined that iron was the cation and oxygen was the anion. After that you can explain how you arrived at the oxidation states you indicated.The oxidation number is the second step but I’m not sure how it should be written.
Which is exactly what you need to learn how to do rather than asking us to do it for you.This is what the question refers to as, “Using the problem-solving strategy” and explaining your answer in a series of steps.
The ion Fe3+, for example, has an oxidation number of +3 because it canacquire three electrons to form a chemical bond, while the oxygen ion O2− has an oxidation number of −2 because it can donate two electrons.Great.
