Last week we learned about naming ionic compounds. There is a cation and an anion. The name of the cation, the metal, goes first and the anion, the nonmetal, goes second with the ending -ide. It also has to balance out to zero. There are two types of these compounds, Type 1 and Type 2 binary compounds. Type 1 binary compounds are your regular metals that will only have one charge and are specific. Type 2 binary compounds' cations have more than one possibility for their charge and are named by using the Roman numeral of their charge.
Also, last week we did a lab that had to do with the visible spectrum and the absorbancy of light at different wavelengths. We messed up on our data, but it was sort of fun changing the test tubes in and out of the machine. Monday we went into the library to make graphs of the data we got from the lab; 2 line graphs and a pie chart! Then we had to answer some questions that were hard, but got help on today. I'm going to miss out on doing the review games on Thursday because of LEAGUE CHAMPIONSHIPS =D and then the test is on Friday...hopefully I'll do well =)
