Chapter 6: Chemical Bonding

Molecules

Build a Molecule – interactive activity in which you build
molecules of varying size and complexity using building block atoms.

http://phet.colorado.edu/en/simulation/build-a-molecule

(Main Idea: Atoms form compounds by gaining, losing, or sharing electrons.)

Molecule Polarity – adjust electronegativity and see the effects on dipoles, electrostatic potential, and electron density at the atomic level, and view models of real molecules.

http://phet.colorado.edu/en/simulation/molecule-polarity

(Main Idea: Atoms form compounds by gaining, losing, or sharing electrons.)

Molecule Shapes – explore molecular geometry and build 3D models of molecules, with single, double, or triple bonds and lone pairs.

http://phet.colorado.edu/en/simulation/molecule-shapes

(Main Idea: Some atoms can share multiple pairs of electrons.)

 

Chemical Bonding

Feature on chemical bonding, covering ionic bonding, covalent bonding (polar and nonpolar), with Flash demos of key concepts.

(Main Idea: Electron-dot notation can represent compounds.)

Hydrogen Bonding – interactive activity; drag molecules near each other to see the attraction of hydrogen to unshared electrons in other molecules.

http://www.chem.arizona.edu/chemt/Flash/hbond.html

(Main Idea: Weak forces exist between molecules.)

Ionic Bonding – a tutorial on ionic bonding, with interactive steps demonstrating the forces of attraction at work between ions, the formation of ionic crystals, and writing the chemical formula for ionic compounds.

http://www.teachersdomain.org/asset/lsps07_int_ionicbonding/

(Main Idea: Ionic bonds form from attractions between positive and negative ions.)

Ionic Bonding – interactive game to test your skills in creating substances by combining cations and anions.

http://www.learner.org/interactives/periodic/groups_interactive.html

(Main Idea: Ionic bonds form from attractions between positive and negative ions.)

Ionic Bonds – a video discussion of ionic bonds, including those that take place in table salt.

Chemical Bonds Quiz – test your knowledge on hydrogen bonds, covalent bonds, and Van der Waals forces.

Molecular Geometry

Molecular Shapes – interactive tutorial the VSEPR theory,
Lewis structures, and 3D visualization of molecular geometry.

http://www.teachersdomain.org/resource/lsps07.sci.phys.matter.molecularshp/

(Main Idea: Negative particles repel and move away from each other; Multiple orbitals can combine to form hybrid orbitals.)

Examples of the molecular geometries that result from the repulsion between pairs of valence electrons, otherwise known as the VSEPR model.
