Molecules and compounds Molecule is a particle of matter, which has two or more atoms chemically combined.
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.7.
STUDY OUTLINE - 1. Introduction 2. Matter 3. Elements 4. Laws & Theories 5. Combinations of Elements Study these topics then write a paper in your own words on each one to document you studies and findings.
Include graphs and diagrams when necessary to aid in the explanation of the topics. General Information Scientist all around the globe use a standard method for naming chemical compounds.
The standards were set up by an international committee sponsored by the IUPAC. Ionic Compound Formula Writing Worksheet. Write chemical formulas for the compounds in each box. The names are found by finding the intersection between the. cations.
Naming Ionic Compounds – Answer Key. Give the name and molar mass of the following ionic compounds: Name. 1)Na 2 CO 3. Chemical Formulas Review: Nomenclature and Formula Writing. Naming Simple Compounds. Naming ionic compounds: The positive ion name is given first (remember, if it’s a transition metal, the Roman numeral indicating its charge is part of its name), followed by the name of the negative ion.

writing formulas of compounds Using the table of oxidation numbers (Table 1), it is not difficult to write the formula of a chemical compound.
There is one important rule that must be remembered.
