In this lab you will use the computer to explore the concepts
introduced in Chapter 7. You can study
light, the Bohr theory of the atom, quantum numbers, electron configurations
and periodic trends. Obtain a “Discover
Chemistry” CD from your instructor and follow the instructions below.
If
using computers other than those located in room AA431, select “start”,
“programs”, “Discover Chemistry”, “Discover Chemistry” for steps 1-3.
