In this video we'll write the correct formula for Nitrous oxide (Dinitrogen oxide) (N2O). To write the formula for Nitrous oxide (Dinitrogen oxide) 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 Molecu... • • Introduction to Formula Writing: • Introduction to Naming and Formula Wr... • For a complete tutorial on naming and formula writing for compounds, like Nitrous oxide (Dinitrogen oxide) and more, visit: • http://www.breslyn.org/chemistry/naming • Drawing/writing done in InkScape (http://www.InkScape.org).
