Chapter 4: Arrangement of Electrons in Atoms

Atomic Model and Quantum Theory

Developing a Model of the Atom – discussion of Rutherford’s and Bohr’s contributions to atomic physics.

http://www.nuffieldfoundation.org/practical-physics/developing-model-atom-nuclear-atom

(Main Idea: Bohr’s model of the hydrogen atom explained electron transition states.)

Quantum Mechanics – a video by PBS including interviews with today’s scientists
discussing the history and innovators in modeling the atom.

http://www.teachersdomain.org/resource/phy03.sci.phys.fund.quantum/

(Main Idea: Electrons have wave-like properties; The speed and position of an electron cannot be measured simultaneously.)

Photoelectric Effect – control the intensity and type of light as well as the target metal to see how light causes the emission of electrons from a target.

(Main Idea: When certain frequencies of light strike a metal, electrons are emitted.)

Electron Configurations

Video explaining the written notation of electron configurations, including the configurations for neon, sodium, and chlorine.

(Main Idea: There are three ways to indicate electron configurations.)

 

Complete Electron Configurations – get some practice writing complete electron configurations with this interactive quiz.

(Main Idea: There are three ways to indicate electron configurations.)

Shapes of Atomic Orbitals – illustrations of the various types of orbital shapes and electron clouds.
