Modeling Atoms and Ions

Unit 3: The Atom
Lesson 3 of 7

Objective: Students will be able to use modeling software to ascertain rules about what makes a stable and neutral atom.

Big Idea: Atoms need to balance protons and neutrons in order to be stable. They are considered neutral when the number of protons and electrons are equal, but charge changes when electrons are gained or lost.
