Why Lesson Planet?
Page one of this resource displays a chart of five different types of solids: metallic, ionic, covalent, molecular, and atomic. The forces that hold the particles together are also described. On page two, junior chemists consider different compounds and determine what type of crystals they form, name predominant molecular forces, and compare boiling points. Answers are included at the bottom of the page, therefore this is best used as a review of concepts.
