It spans several pages, but it is mostly revision and has been included as a reference for learners.
Phosphate ion PO Pattern 1: For instance, if you know nitrate is NO3-,then nitrite is NO If you know phosphate is PO,then you know phosphite is PO You can also use the prefixes hypo- and per- with the chlorate series.
Hypochlorite is a double whammy: You can also substitute the other halogens for Cl and make additional sets of the series.
The -ates with charges less than negative 1 that is, ions with charges of -2, -3, etc. HCO3-is called either the bicarbonate ion or the hydrogen carbonate ion.
These are named hydrogen phosphate and dihydrogen phosphate, respectively. That means you need to see the naming acids rules. The following periodic table will also come in handy. Working backward from the halogens, or 7A family, the oxidation states are most commonly -1, while the 6A family is -2, and the 5A family is Naming acids is extremely easy if you know your polyatomic ions.
There are three rules to follow: HCl is hydrochloric acid; H2S is hydrosulfuric acid. When you see an acid name beginning with hydro- think: HCN is an exception since it is a polyatomic ion without oxygen, so it is named hydrocyanic acid.
If the acid has an -ate polyatomic ion after the H, that makes it an -ic acid. H2SO4 is sulfuric acid. When the acid has an -ite polyatomic ion after the H, that makes it an -ous acid. H2SO3 is sulfurous acid.Get used to what part of an element’s name is the “root” early, because it’s not always easy to tell by looking!
Naming Ionic Compounds. Recall that ionic compounds consist of a positively charged cation and a negatively charged anion. Ions (of either variety) may contain either a . Writing Formulas & Names for Polyatomic Ionic Compounds / 2 Writing Formulas for Polyatomic Compounds The formula writing and naming of polyatomic ionic compounds is similar to .
Water, H 2 O. Water is a simple compound with a set of unique properties that are essential for life. The chemical formula for water is H 2 O and its proper chemical name is dihydrogen monoxide.
Water contains two parts hydrogen to one part oxygen. Naming Compounds and Writing Formulas Reading Strategy Predicting Copy the table. Before you read, Naming binary ionic compounds, such as sodium chloride and cadmium iodide, is easy.
The names The name for the anion uses part of. When the name of an anion that is part of an acid ends in -ite, the acid name includes the suffix Apply the rules for naming and writing formulas for binary ionic compounds. | Apply the rules for naming chemical compounds by using a flowchart.
Apply the rules for naming and writing formulas for compounds with. Expert Reviewed. How to Name Chemical Compounds. Three Methods: Naming Ionic Compounds Naming Polyatomic Compounds Naming Covalent Compounds Community Q&A Naming basic chemical compounds is essential if you want to succeed in chemistry, since the name of the compound clearly defines what it is.
