| Video Discription | In this video we'll write the correct formula for Chromium (II) bromide (CrBr2). To write the formula for Chromium (II) bromide we’ll use the Periodic Table and follow some simple rules. ---Keys for Writing Formulas for Compounds with Transition Metals--- 1. Write the symbol and charge for the transition metal. The charge is the Roman Numeral in parentheses. 2. Write the symbol and charge for the non-metal. If you have a polyatomic ion, use the Common Ion table to find the formula and charge (see https://youtu.be/N4N1Njh7nCo). 3. See if the charges are balanced (if they are you're done!) 4. Add subscripts (if necessary) so the charge for the entire compound is zero. 5. Use the crisscross method to check your work. Notes: - Don't write the subscript '1'. - If you use the criss-cross method and end up with something like Ca2S2 you'll need to reduce the subscripts to Ca1S1 which we write CaS. - It is possible to have two polyatomic ions such as NH4NO3. In this case find and write both names as found on the Common Ion Table. ---Formula Writing Resources--- Finding Ionic Charge: https://youtu.be/N4N1Njh7nCo Memorizing Polyatomic Ions: https://youtu.be/vepxhM_bZqk Criss-Cross Method: https://youtu.be/VnzIqpdEims For a complete tutorial on naming and formula writing for compounds, like Chromium (II) bromide and more, visit: http://www.breslyn.org/chemistry/naming Drawing/writing done in InkScape.
