<center><b>Chemistry - Naming Molecular Compounds</b></center><br> <br> <b>A. Chemical Name to Chemical Formula</b><br> 1. Write down the symbol of the first non-metal element and the second non-metal.<br> 2. Using the table of prefix below, the subscript is the number from the prefix. For no prefix, it is a subscript of 1.<br> <i>Example: Disulfur heptachloride</i><br> Step 1 S Cl<br> Step 2 S<sub>2</sub>Cl<sub>7</sub><br> <br> <i>More Examples:</i> Carbon disulfide, Decaoxygen pentanitride (Answer: C<sub>1</sub>S<sub>2</sub>, O<sub>8</sub>N<sub>5</sub>)<br> ----------------<br> <center><b>Prefix Table</b></center><br> mono - 1<br> di - 2 <br> tri - 3<br> tetra - 4<br> penta - 5<br> hexa - 6<br> hepta - 7<br> octa - 8<br> nona - 9<br> deca - 10<br> -------------------<br> <b>B. Chemical Formula to Chemical Name</b><br> <br> 1. Write down the first non-metal name.<br> 2. Add prefix from table (1st letter needs capital) End of 1st word.<br> 3. Write down the second non-metal name. Add prefix from table (no capitals in 1st letter). <b>Important</b>: If fitrst element has subscript of 1, you Do not add "mono".<br> 4. replace ending with "ide".<br> <i>Example</i>: F<sub>2</sub>O<sub>1</sub><br> Step 1 Fluorine <br> Step 2 Difluorine<br> Step 3 monoxygen Step 4 Difluorine monoxide<br> <br> <i>More Example</i>: C<sub>1</sub>O<sub>1</sub>, N<sub>3</sub>P<sub>8</sub> (Answer: Carbon monoxide, Trinitrogen octaphosphide)<br>
