Structure and Properties


Lesson 1: Atomic Structure


Primary Learning Goals

I can explain how experimental observations and inferences by Ernest Rutherford and Niels Bohr contributed to the development of the planetary model of the atom.

I can describe the quantum mechanical model of the atom in terms of shells (energy levels), subshells (sublevels), orbitals, and electron spin.


Work

1. Read sections 3.1, 3.2, 3.3, and 3.4 in the textbook.

2. In-class lecture “Atomic Structure” (summary slides).
