How to Write the Formula for Mercury II acetate

In this video well write the correct formula for Mercury II acetate :HgCH3COO2. To write the formula for Mercury II acetate well use the Periodic Table a Common Ion Table see and follow some simple rules. Because Mercury II acetate has a polyatomic ion the group of non-metals after the metal well need to use a table of names for common polyatomic ions in addition to the Periodic Table. ---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 3.
See if the charges are balanced if they are youre 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: - Dont write the subscript 1. - If you use the criss-cross method and end up with something like Ca2S2 youll 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. For a complete tutorial on naming and formula writing for compounds like Mercury II acetate and more visit: Drawingwriting done in InkScape.
