7. Quantum Theory (4 lessons)

Concepts The Bohr model is only an approximation of real electron behaviour.  Actually, electrons do not “orbit” the nucleus but exist in probability clouds at different energy levels. Unpaired electrons in atomic orbitals produce ferromagnetic behaviour. Skills Quiz 7a Determine the electron configuration of an atom in its ground state. Relate ground-state electron configurations to theContinue reading “7. Quantum Theory (4 lessons)”

6. Organic Chemistry (10 lessons)

Concepts Because of its half-full valence shell and medium electronegativity, carbon can form an extraordinary number of covalent compounds. Organic (carbon-based) compounds form the chemical basis of all life on Earth. Organic compounds can be classified (and named) based on the length and arrangement of their carbon chains, and by the “functional groups” attached to theContinue reading “6.

5. Solutions (15 lessons)

Concepts When substances are mixed, mass is conserved, but volume might not be because particles fill gaps between each other. “Like dissolves like.” Whether a solute can dissolve in a solvent depends on a balance of attractive forces (solute-solvent vs. solvent-solvent and solute-solute). This means that polar substances tend to dissolve in other polar substances,Continue reading “5. Solutions (15 lessons)”
