Bond References.pdfBond Reference Answers.pdfDestructive Testing of Metallic Bonds Intro Lab
The intro lab for this unit involves simple destructive testing on metallic bonds - namely those involved in paper clips and hairpins. This destructive testing has some interesting analogies to the test research done on metal samples from the Titanic.
Additional Titanic facts are in the Intro Lab shown above!
Skeptical Questions In Science
Skeptical Questions In Science
The skeptical question topic for this unit involves the topic of "metal-eating bacteria". Skeptical questions are thoughtful "Why-based" questions which address biases in scientific material. This type of question is not seeking scientific facts.

Ionic vs Covalent Bonds
Ionic vs Covalent Bonds
Structural characteristics of ionic and covalent bonds influence characteristics we see on a macro level. This chart shows a listing of properties and characteristics associated with ionic and covalent bonds. Two charts are included to provide a diverse view of these characteristics.
Ionic vs Covalent Bonds.pdfThis video might help with a brief introduction to differences in ionic and covalent bonding.
This is the point in the unit where the first 80% quiz occurs. This quiz covers electron stability, why atoms bond, and bond type determination.

Bond Model Drawings
Bond Model Drawings
Bond model drawings are an attempt to represent the structure of bonds based on their ionic or covalent characteristics. Both ionic bonds and covalent bonds are drawn using a dot diagram format with slight variations.

VSEPR Covalent Molecule Adjustments
VSEPR Covalent Molecule Adjustments
Most of the covalent drawings completed in class are two-dimensional representations of a three-dimensional molecule. In order to address this, VSEPR adjustments are made to covalent drawings. These adjustments allow for considering the effect of electron repulsion on molecular shapes. Examples of the most common VSEPR shapes are included on the reference page for this unit.

Polarity
Polarity
When determining bond types, some bonds end up as "polar covalent" while others become "non-polar covalent". Polarity is based on the symmetry of the molecule according to where the electrons are located at any given point in time. "Dissolving" occurs when the polarity of the solvent and the material being dissolved match. In other words, "LIKE DISSOLVES LIKE".
Polarity determines the ability of one substance (the solvent) to dissolve another substance (the solute).
Polarity determines the ability of one substance (the solvent) to dissolve another substance (the solute).
Water is the "universal solvent" meaning it is the first choice of most people for cleaning or to mix with other cleaners. As a solvent, water is HIGHLY POLAR, meaning it works best to dissolve other highly polar materials.
How well does water dissolve the following...?
