Ionic and Covalent Structure Ionic compounds form a crystalline lattice - a repeating pattern of ions. If you are doing this sensibly, you will only be looking at one or two types of compounds at a time. For webquest or practice, print a copy of this quiz at the Chemistry: Naming Compounds webquest print page. Prefixes aren’t employed by compounds. Each of these three has its own rules that cannot be mixed and matched. The name of a monatomic cation is simply the name of the element followed by the word ion.Thus, Na + is the sodium ion, Al 3 + is the aluminum ion, Ca 2 + is the calcium ion, and so forth.. We have seen that some elements lose different numbers of electrons, producing ions of different charges (Figure 3.3). III. Naming Compounds What’s it Made of? Second, look at the subscript of each element to determine which prefix to use. Water If yes, it’s an ACID so follow the acid rules –b. The name starts with the title of the very first component carbon that’s specific. •1st –determine if the compound is an acid –a.

Covalent compounds form individual molecules that are not connected to each other. If you are given a formula, is the first element hydrogen? When naming compounds, you need to understand these different rules, as well as how to spot clues that will help you properly name the compounds. First of all, decide if the compound is ionic, covalent-molecular or an acid. The name is built from the elements and the construction of the molecule. Example. Note that the double bond takes precedence in naming. Just as each distinct compound has a unique molecular structure which can be The name of a monatomic cation is simply the name of the element followed by the word ion.Thus, Na + is the sodium ion, Al 3 + is the aluminum ion, Ca 2 + is the calcium ion, and so forth.. We have seen that some elements lose different numbers of electrons, producing ions of different charges (Figure 3.3). This can be paraphrased as: The algebraic sum of the oxidation numbers of the elements and polyatomic ions in a chemical compound is zero.

Naming basic chemical compounds is essential if you want to succeed in chemistry, since the name of the compound clearly defines what it is. Today you will find out why CO is named that way. NaCl → Na+ → sodium and Cl− → chloride → NaCl = sodium chloride Don’t use “mono” for first name, but always for second name. Each type of compound has its own rules for naming it. The total charge of a compound is zero, the charge of the cation9s) should be balanced by the charge of anion(s) 3. Naming Binary Compounds (compounds made of two different atoms): 1. why?
