Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.

This site talks about ionic, polar covalent, and non-polar covalent bonding.

By working through this web-based activity, students differentiate between ionic, non-polar covalent, and polar covalent bonds. Specifically, distinctions are made between bonding types based on orbital shapes and electronegativity...

This section of the lesson module focuses on covalent bonds, which are formed between non-metal atoms that share a pair of electrons. It includes links to a video and a test. Other types of chemical bonds are covered elsewhere in the...

In this tutorial, students learn about ionic and covalent bonds and predict which elements will form which type of bond. Includes interactive exercises as well as videos.

[Free Registration/Login may be required to access all resource tools.] Describes the metallic bond and properties of metals. Includes review questions.

Explore the differences between chemical and physical changes, including some examples at the atomic level.

Lesson plan in which students design an experiment to determine if different types of liquids affect the amount of dissolution of an M&M candy shell.
