Electron Configuration

Unit 3: The Atom
Lesson 6 of 7

Objective: Student will be able to describe how electrons are organized for the first 20 elements, and to identify and model valence electrons.

Big Idea: An atom’s electron configuration can be determined by knowing how many electrons are in the atom, and the order of electron filling. Valence electrons play a critical role in chemical bonding and can be represented with Lewis dots.
