Teaching ionic and covalent bonds? Focusing on binary compounds but still need a quality review of nomenclature and writing formulas? Then this worksheet is for you! This worksheet contains a mix of covalent and ionic naming and writing formulas. I personally use it as a summarizer after I've taught both covalent and ionic bonds. This is geared towards Physical Science students as we only cover binary compounds. But this worksheet could be used in chemistry early on in nomenclature before getting into using roman numerals and polyatomic ions.
