Naming And Writing Binary Compounds Worksheets - Learny Kids Start studying Naming Binary Compounds (ionic). Learn vocabulary, terms, and more with flashcards, games, and other study tools. Naming Binary Compounds (ionic) Flashcards | Quizlet To predict the formula of the ionic compound, we use the fact that chemical compounds are always electrically neutral—they have the same total quantities of positive and negative charges. In this case we must have equal numbers of Ca2+ and O2- ions, and the empirical formula of the compound is CaO. A molecular formula is for a compound which exists as a discrete molecule, like H2O, CO2 or C12H22O11. Since compounds which exist as networks of atoms don’t exist as discrete molecules, the can’t really be called “molecular formulas.” Naming Binary Molecular Compounds. Binary molecular compounds. Composed of two nonmetal elements. No ions are present, just molecules, therefore ionic charge cannot be used to write names or formulas. If we named molecular compounds as though they were ionic compounds there would be no way to differentiate between two or more compounds with the ... An empirical formula is the lowest whole-number ratio of elements in the compound. 3. What kinds of compounds (molecular, ionic, network) can be represented with a molecular formula?
