Naming Binary Molecular Compounds
__Binary Compound__- compound that contains two elements

When naming binary compounds you must consider four things The prefix mono is never used when naming the first element. Also, if the name of the prefix end with an a or o and the second element begins with a vowel than the end of the prefix is often dropped (see example 1).
 * 1) Left to Right- When naming ionic compounds, the element furthest to the left of the periodic table is written first. The exception is oxygen. Oxygen is always written last except when it is combined with fluorine.
 * 2) Bottom to Top- Also, when naming binary compounds if the elements are in the same group, then the one on the bottom is named first.
 * 3) The element that is named last will end in -ide.
 * 4) Greek prefixes (see the list below) are used to determine the number of atoms of each element.

1- Mono 2- Di 3- Tri 4- Tetra 5- Penta 6- Hexa 7- Hepta 8- Octa 9- Nona 10- Deca

Examples 1. Di chlorine mon oxide (the second o in mon**o** was dropped, make sure you don't say mon**o**oxide) 2. Nitrogen tri fluoride 3. Tetra phosphorus Deca sulfide
