Naming Ionic and Molecular Compounds
Before starting to learn how to name the compounds, you must know and have a few things. First, you must learn the prefixes, which are in the header picture. Next, you MUST have a periodic table!
Now, before you start reading, just know that this is fun chemistry! Once you get it, it's like solving a murder mystery!
There is a difference between ionic and covalent and molecular bonding. Ionic bonding is the bonding of ions by gaining or losing electrons. You will see a - or + sign after some compounds, indicating the gain or loss of electrons. Molecular and covalent compounds are the sharing of electrons which forms molecules.
Next, you must know when, and when NOT to use prefixes. For starters, if you did not read the important questions section, prefixes are used to represent, in written form, the subscript of an element.
There are several types of ionic compounds which should be well known in this unit. Here is a picture of the periodic table and the common ions:

Now, let's get straight to the naming.
The prefixes are:
EXAMPLE: CO2 which is composed of a carbon and two oxygen. Both are NON-METALS and when using the prefixes, you would say: Carbon Dioxide. If the first element has no subscript, it is right to say its name, NOT monocarbon.
And example of when you would say the first element with a prefix is N2O5, which would be dinitrogen pentoxide. Note: every formula ends in -ide.
See, that was not too hard, right? If you understand, then let's move onto acids!
