Lecture outline:
- The periodic table and its historic development
- Atomic radius, ionic radius
- Electron affinity, ionization energy, and electronegativity
- Overview of the main groups on the periodic table
Hydrogen lab
We will make and test hydrogen gas. A classic lab exercise making and collecting this important gas, and testing it under different conditions.
