![]() Remember that the second word ends in -ide. That name tells you that you have one carbon (C) atom and one oxygen (O) atom (you can also use the prefix MONO to say one atom). Most simple compounds only have two words in their names. Let's put these ideas together! Remember, we're only talking about simple compounds with no metal elements. The naming system in chemistry works the same way! You may know about a pentagon, a hexagon, or an octagon. So when you have three chlorine atoms, you would name it trichloride. Given the chemical formula, what is the name for the covalent compound COVALENT COMPOUNDS. It's like this.ĭo you notice anything about the chalkboard? You can see that the prefixes are very similar to the prefixes of geometric shapes. When you are working with non-metals like oxygen (O) and chlorine (Cl), the prefix (section at the beginning of the word) of the second element changes based on how many atoms there are in the compound. Silicon and germanium are semimetals (metalloids). The second word tells you the second element and how many atoms there are in the compound. Of the Group 14 elements, only carbon and silicon form bonds as nonmetals (sharing electrons covalently). The first word is the name of the first element. An exception to this rule occurs when hydrogen is bonded to a metal. When you have two different elements, there are usually only two words in the compound name. TABLE 6.2 Names and formulas of some common ionic compounds. There are some advanced ways of naming things that we're going to skip right now. We're going to show you some of the basics. The process of naming compounds is just a set of rules.
