When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. Basic Naming Convention First well cover how to name molecules with two elements binary compounds.

You should recognize the MnO 4-ion as permanganate.

How to name compounds with three elements. A ternary ionic compound is an ionic compound composed of three elements. For both molecular and ionic compounds change the name of the second compound so it ends in ide. H 2 PO 4- Dihydrogen phosphate.

Ionic compounds are named by stating the cation first followed by the anion. Mixtures do notWater is always 888 O and 112 H by weight. Water carbon dioxide and table salt are three examples for.

Compounds have a constant composition. In the simplest way you can define a chemical compound as a substance that is made up of two or more elements. X 3-1 0.

Mono- indicates one di- indicates two tri- is three tetra- is four penta- is five and hexa- is six hepta- is seven octo- is eight nona- is nine and deca is ten. With my strategy and step by step examples you will be naming compounds like a pro in no time. Positive and negative charges must balance.

The name of a compound with two elements has two words. To avoid this cancel and sign in to YouTube on your computer. HSO 4- Hydrogen sulfate or bisulfate.

Full screen is unavailable. For example the compound FeCl 3 which contains Fe 3 is named iron III chloride. Add the name of the non-metal with an ide ending.

If the element comes in front of the ion group the name of the element is simply added to the beginning of the compound name. Videos you watch may be added to the TVs watch history and influence TV recommendations. Not all ionic compounds are composed of only monatomic ions.

These are formed from non-metals that share electrons. Ternary compounds are composed of three or more elements. Fluorine fluoride.

This removes some of the complications and confusions of the older hypo- -ite -ate per- prefixes and suffixes. It is still common to see and use the older naming convention in which the prefix bi- is used to indicate the addition of a single hydrogen ion. The ratio of each element is usually expressed by a chemical formula.

To get the first word we use the name of the first element or the element to the left of the formula. CrCl 3 chromium III chloride. Naming covalent compounds with three elements follows these similar rules.

Here is a video which summarizes how to name ternary 3 elements ionic compounds. The name is built from the elements and the construction of the molecule. HCO 3- Hydrogen carbonate or bicarbonate.

The law of constant composition states that the ratio by mass of the elements in a chemical compound is always the same regardless of the source of the compound. Lithium which is a cation and hydrogen phosphate. Therefore its name is Li 4 HPO 4.

Associate whatever elements is attached to the group ion and name accordingly. To add the -ide ending just drop the 1 or 2 syllables -ine in this case and add -ide instead. Some anions have multiple forms and are named accordingly with the use of roman numerals in parenthes.

On the other hand the compound FeCl 2 which contains Fe 2 is designated as iron II chloride. A compound is made up of two or more elements chemically bonded together. For example water H2O is a compound consisting of two hydrogen atoms bonded to an oxygen atom.

The cation the anion or both is a polyatomic ion. Here is a list of examples of compounds made of two elements. Build compound names based off the list.

In a typical ternary ionic compound there is still one type of cation and one type of anion involved. Add an ide to the end of the second compounds name. Therefore the names of binary compounds containing metals such as these must include a Roman numeral to specify the charge on the ion.

When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. For example lithium hydrogen phosphate contains three elements. If playback doesnt begin shortly try restarting your device.

The second component of an ionic compound is the non-metal anion. Mono- indicates one di- indicates two tri- is three tetra- is four penta- is five and hexa- is six hepta- is seven octo- is eight nona- is nine and deca is ten. Potassium bromate or potassium bromate V The preferred IUPAC names include the oxidation state of the element in the oxo-anion.

Write the non-metals name with an -ide ending. As you would in the other cases specify the formula charge and number of each ion. Naming compounds have never been so simple.

K is potassium so the compound is named potassium permanganate. The law of constant composition can be used to distinguish between compounds and mixtures of elements.
