Physical Science 20 - Feb 6

Today in class we learned how to use the Stock naming system when encountering compounds that involve elements that can have multiple cationic charges.  This system involves using Roman numerals to denote the positive charge that the ion has.  We also discussed the differences between this and the classical systems which utilized the latin names of the elements.

We also learned how to name hydrated compounds.  This wasn't much different than what we have already done.  We just have one more step of adding a name for the water molecules that are in the compound.

Students spent the majority of class working on Assignment C3, C4 and C5 which are all going to be checked for completion on Monday.

On Monday we will look at how to name acids as well as starting to learn how to name organic compounds.
