The first thing to recognize here is that you're dealing with an ionic compound made up of iron, "Fe", a metal, and sulfur, "S", a nonmetal. The mineral pyrite, or iron pyrite, is an iron sulfide with the formula FeS2. Who told you it was called that? No such thing as Ni(IV). If you wanted to be pedantic, it's nickel(II) disulfide, but there isn't any other kind, so most of the time chemists just leave out the (II), because it's not actually ambiguous. Who told you that? The S2^2- is the persulfide, and is the analog of peroxide, O2^2-. From electronegativity, it should be covalent as the $\Delta\chi=0.7$ which is less than $1.5$ and thus said to make covalent bonds and therefore be a covalent compound. What is the ground-state electron configuration for Cr? FeS2 is the chemical formula for iron and sulfur. For the best answers, search on this site https://shorturl.im/twFnc. It is this problem that Alfred Stock set out to remedy when he developed what we now call the "Stock system" of chemical nomenclature. When did organ music become associated with baseball? Thanks for contributing an answer to Chemistry Stack Exchange! Why are bonds ionic when the electronegativity difference between bonded atoms is greater than 1.7? Assign the electrons from each bond to the more negative bond partner identified by ionic approximation. Iron Pyrite can also help to balance the hardness and friction coefficient of brake pads. I have a 1993 penny it appears to be half copper half zink is this possible? What is the answer to this tricky chemistry problem? Pyrite is the most common of the sulfide minerals.
