Document Summary
Mono, di, tri, tetra, penta, hexa, hepta, octa, nona, deca. Nomenclature: name metal/polyatomic ion and then add nonmetal and end it off with ide, if the cation has multiple charges, make sure to add roman numerals. Oxyanions: end with an ate for example co3^2 would become hco3- (hydrogen carobante) Naming acids: for halogens simply add hydro chemical name acid. Usually the retarded method of naming involves the mass # being on top and the atomic number being on the bottom. Electrons= number of protons +- the charge. Question) 44. 4% c, 6. 21% h, 39. 5% s, 9. 86% o and molar mass is 324g. Step 1) assume they are all in grams and divide by their molar masses. Step 2) divide all the moles by the smallest number of moles. Step 3) if the numbers are in decimals make sure to multiply all the numbers to get good numbers. Step 4) obtain molar mass for empirical formula and divide it by molecular.
