This lab requires the use of computers (one per pair or trio of students) and Microsoft Excel (or other spreadsheet program).
Students are given data on the Ionization Energy of various elements as well as their Atomic Radius and Atomic Number.
Students input this data into Excel and construct a line graph showing the periodic trends of ionization energy both across periods and down groups. It's a great way for students to visually analyze the relationship between atomic radius, atomic number, and ionization energy.
My labs are straightforward. Some of them are paper labs, but the ones that involve significant laboratory setup or calculations to be made on the part of the teacher are written about in a Teacher Notes section at the end of those particular labs. I use relatively safe and inexpensive chemicals. Of course, safety precautions are always noted at the beginning of the lab.
