The following episode looks at writing formulas for binary ionic compounds we look at something i like to call the 5 step cross over rule download this episode for free from itunes by typing in the search window. Writing formulas for binary molecular compounds is like decoding a message if you can name a compound from its formula, then it's easy to do the reverse we will rely on some of the same rules and use essentially the same four steps. Formulas and nomenclature of ionic and covalent compounds adapted from mcmurry/fay, section 210, p 56-63 writing formulas of ionic compounds nomenclature of ionic and covalent compounds a binary compound is a compound formed from two different elements there may or may not be more than one of each element.
