It is still used for carbon monoxide due to the term being in use since early chemistry. Weak bases made of ionic compounds are also named using the ionic naming system. In this compound, the cation is based on nickel. Do you use prefixes when naming covalent compounds? Key Terms 3 What are the rules for naming an ionic compound? %PDF-1.3 1. Ionic compounds with transition metals will contain prefixes to denote oxidation states, but those are not prefixes. the ions in ionic compounds have known charges that have to add to zero, so the numbers of each ion can be deduced. These ions are named by adding the word hydrogen or dihydrogen in front of the name of the anion. Legal. For example, we might think to call C2H6 dicarbon hexahydride, but in reality its called ethane. Legal. Try these next 3 examples on your own to see how you do with naming compounds! How do you name alkenes with two double bonds? Carbon monoxide contains both carbon and oxygen, which is indicated by the prefix mono = 1. HF (g) = hydrogen fluoride -> HF (aq) = hydrofluoric acid, HBr (g) = hydrogen bromide -> HBr (aq) = hydrobromic acid, HCl (g) = hydrogen chloride -> HCl (aq) = hydrochloric acid, H2S (g) = hydrogen sulfide -> H2S (aq) = hydrosulfuricacid. When two or more elements share electrons in a covalent bond, they form molecular compounds. Write the non-metal's name with an "-ide" ending.
