Answer 2

While there are many thousands of different chemical compounds there is a very definite system of nomenclature whereby we can name or write chemical formulas for most compounds. We divide the compounds into two main types – binary compounds and ternary compounds.

 

Binary Compounds

 

All true binary compounds contain only two elements. The name of every binary compound ends with “ide.” Binary compounds come in three types. They are:

            Type I............. the metal forms only one type of cation

            Type II............ the metal forms two or more types of cations

            Type III.......... contains only nonmetals

We will look at each type, one at a time.

 

Type I Binary Compounds

 

For Type I binary compounds the metal present can be found in either Group 1 or Group 2 on the periodic table. The naming system for this type of compound is quite simple and is found below.

 

Rules for naming Type I binary compounds

1.         The cation is always named first and the anion second.

2.         A simple cation (obtained from a single atom) takes its name from the name of the element.

3.         A simple anion (obtained from a single atom) is named by taking the first part of the element name (the root) and adding the letters “IDE.”

4.         Write the name for the compound by combining the names of the ions.

 

Examples:

Name the compound RbI.

·        Rb is the chemical symbol for rubidium.

·        I is the chemical symbol for iodine, whose root is “iod.” Add the “ide” ending to get iodide.

·        Put the pieces together to get the name rubidium iodide.

 

Name the compound CaO.

·        Ca is the chemical symbol for calcium.

·        O is the symbol for oxygen, whose root is “ox.” Add the “ide” ending to get oxide.

·        Put the pieces together to get the name calcium oxide.

 

Name the compound Li3N.

·        Li is the chemical symbol for lithium.

·        N is the chemical symbol for nitrogen, whose root is “nitr.” Add the “ide” ending to get nitride.

·        Put the pieces together to get the name lithium nitride.
