Drawing Particle Diagrams
Learning Objective
I can draw particle diagrams to represent different states of matter and chemical reactions.
Key Concepts
In particle diagrams, spheres represent individual atoms, and the box represents the container they are in.
If a particle diagram has spheres of the same size and color, it represents an element, but if two or more are touching, it is a diatomic element.
A solid in a particle diagram has a structured pattern, while a liquid has a random pattern, and a gas fills the entire space.
Practice Questions
This lesson includes 8 practice questions to reinforce learning.
