This interactive activity from ChemThink takes a closer look at a covalent bond: how it is formed and how the sharing of two electrons can keep atoms together.

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 activity helps students review basic covalent nomenclature.

Students discover that ionic bonding occurs when electrons are transferred from one atom to the other and not shared as in covalent bonding.

This interactive activity developed for Teachers' Domain demonstrates how attractive forces between atoms create chemical bonds, resulting in the formation of molecules and compounds.

This inquiry activity introduces chemical and ionic bonds and allows students to investigate an unknown situation, make hypotheses, and share data.

Problem sets, tutorials, and activities related to biochemistry.

This instructor led activity will produce a partially filled periodic table that contains electron-dot models for the first twenty elements in the appropriate boxes. It will be used as a visual tool for young scholars to connect concepts...

In this interactive activity from the NOVA Web site, animations explain different aspects of the properties of metal.

Students will use colored fruit loops to organize valence electrons to develop and master the basics of Lewis Dot diagrams. They will develop processing and critical thinking skills and also master a model of bonding.

In this activity, students construct models of molecules using marshmallows and gum drops.

In this interactive activity from ChemThink, students will learn about covalent molecules and how the VSEPR theory predicts the shapes of covalently-bonded molecules.

Students develop their own water molecule model to help them understand the idea that water has a slight positive charge at one end of the molecule and a slight negative charge at the other.
