How to Write the Formula for Chlorine dioxide

In this video we'll write the correct formula for Chlorine dioxide (ClO2). To write the formula for Chlorine dioxide we’ll use the Periodic Table and follow some simple rules. When we have a non-metal and a non-metal we have a molecular compound (sometimes called covalent). Molecular compounds are some of the simplest to name. Keys for Writing the Formulas for Molecular Compounds: Write the element symbol for both elements. Place a subscript after each element according to its prefix. Note: Don’t write the subscript '1'. --------- Prefixes mono- 1 di- 2 tri- 3 tetra- 4 penta- 5 hexa- 6 hepta- 7 octa- 8 nona- 9 deca- 10 --------- Caution: We only write "mono" for the second element in a molecular compound. So CO would be carbon monoxide. Monocarbon monooxide is incorrect. --Formula Writing Resources-- • Writing Formulas for Molecular compounds:    • Naming and Formula Writing for Molecular C...   • Introduction to Formula Writing:    • Introduction to Naming and Formula Writing   For a complete tutorial on naming and formula writing for compounds, like Chlorine dioxide and more, visit: http://www.breslyn.org/chemistry/naming Drawing/writing done in InkScape (http://www.InkScape.org).
