Periodic Table Blocks: Investigation
This learning activity is meant to allow you to investigate the periodic table, to see how elements are organized and to observe any patterns relating to electron placement.
For this learning activity you will need to make sure you are comfortable with the following concepts:
- Aufbau Principle: States that electrons will fill up orbitals starting with the lowest energy orbital available
- Aufbau Diagrams: Tool to help organize orbitals in order of increasing energy. Make sure you are able to both read an Aufbau Diagram and produce one yourself
- Electron capacity of each subshell type: Recall from earlier lessons, each orbital can hold 2 electrons; furthermore, you need to remember how many of each orbital type exist in a given shell. For example, the n = 3 shell has 5 d-orbitals which can hold 10 electrons total.
- n = 1: 1 s-orbital
- n = 2: 1 s-orbital; 3 p-orbitals
- n = 3: 1 s-orbital; 3 p-orbitals; 5 d-orbitals
- n = 4: 1 s-orbital; 3 p-orbitals; 5 d-orbitals; 7 f-orbitals
- n = 5 (and up): 1 s-orbital; 3 p-orbitals; 5 d-orbitals; 7 f-orbitals
