I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...

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...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Is your class in a quandary over quantum numbers? Change things up by adding games to the mix! Science scholars discover the shape, number of electrons, and number of orbitals in the s, p, and d sub-shells using an interactive.

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

Explore the interactions between various combinations of two atoms. Observe the the total force acting on the atoms or the individual attractive and repulsive forces. Customize the attraction to see how changing the atomic diameter and...

Students draw and interpret Lewis dot diagrams for individual atoms and both covalent and ionic compounds.

Provides good objectives to go along with a text discussion of hybridization. Complete with illustrations, charts, and graphics.

Short slide show provides basic information about drawing Lewis dot structures for covalent compounds. Starts with anatomy of the atom, and then shows the relationship between atomic particles and the Periodic Table of Elements. Offers...

In this module Activity 4 investigates How are bonds formed and broken? This activity explores the relationship between energy and the formation and breaking bonds, using the ideas of energy transfer and conversion.

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

In this module Activity 3 investigates When atoms get close to each other, what happens to their potential energy? This activity applies energy concepts to compare the potential energy of atoms that are bonded as molecules with the...

This digital textbook covers core chemistry concepts and includes interactive features, real-world examples, and videos.
