Notes on module 4, and random stuff Dr. Bill said in class:
matter: d=m/v matter is anything with density (not destiny)
Atoms: a-tom tom=cut tomogram, subway turkey slicer, also brain slicer
molecules: more than one atom connected
elements: see the periodic table, always capital letter then smaller letter as needed
Names often arcane
All elements in same column are chemically similar: Sr 90, I 131
Antimony (Sb) kills monks
Carbon 14/6 6 protons, 6 electrons (if neutral), 8 neutrons
Imbalance of neutrons associated with radioactivity
Radioactive half-lives-THC example of ascending total concentrations
(next: ionic and covalent bonds)
(next: polar and non-polar molecules)
Water: cohesion-water to water adhesion-water to something else
Capillary action: basis of all roots, trees, fibers, long hair
Salt the earth: desertification, water follows salt
next:
pH and pOH, -log10 [H]
organic and inorganic
ionic and covalent bonds
polar and non-polar molecules
CHO-simple or complex chains of CHO
Fats-Glycerol backbone with chains of CHO
Proteins-Nitrogen base with chains of CHO-puppy food, green grass
DNA/RNA
Phospholipid bilayer
cells
