Why do we name compounds?
The primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which chemical compound the name refers to: each chemical name should refer to a single substance.
What are chemical formulae?
These are called chemical formulae. In the first three examples, the ratio of the elements in each compound is 1:1. So, for FeS, there is one atom of iron for every atom of sulfur in the compound. In the last example ( H 2 O) there are two atoms of hydrogen for every atom of oxygen in the compound.
How do you name a compound with elements?
In the example of iron sulfide that was used earlier, the compound name is a combination of the names of the elements but slightly changed. The following are some guidelines for naming compounds: The compound name will always include the names of the elements that are part of it.
