We reviewed the notation methods of electron configuration based on the element's location in the s, p, d, or f blocks and introduced the idea of basing the electron confiuration on the previous period's noble gas.
The aufbau diagram was introduced, and electron placement according to the Pauli Exclusion Principle and Hund's Rule followed. There will be several examples of these problems worked on tomorrow.
We finished with a description of valence electrons, and how they are used in chemical bonding. We will use electron-dot diagrams (Lewis dot structures) to symbolize our valence electrons in the s and p orbitals.
