Presentation Transcript

  1. Warm Up 10-29 Which frequency of visible light has the lowest amount of energy? Which has the highest?

  2. Electron Config. Rules • An orbital can hold 2 electrons max. • Aufbau Principle: Lower orbitals and energy levels fill up before higher ones. • Hund’s Rule: All orbitals get one electron before they get a 2nd. • Pauli Exclusion Principle: If two electrons are in the same orbital, they must have opposite spins.

  3. Left Side Practice • Write the electron configurations for: • Boron (B) • Sulfur (S) • Calcium (Ca) • Nickel (Ni) • Krypton (Kr) • Silver (Ag) • Iodine (I)
