FUNDAMENTALS OF CHEMISTRY CHAPTER 2
Chem review Chemical bonding (its all about the electrons) water and polarity (like dissolves like) pH - acids and bases (7 is neutral) organic chemistry (4 bonds on every carbon)
Chemical Building Blocks • Atoms- smallest functional unit of matter • Elements/Isotopes (dif #s of neutrons) • Molecules - covalently bonded atoms • Compounds - mixed bonded atoms
Atomic Structure • Proton +charge • Neutron 0 • Electron -
Atomic Properties • Atomic Number • Atomic Weight • Moles
Chemical Reactions • Catabolic - break down (usually gives off energy) • Anabolic - build up (usually requires energy)
Important Biological Molecules • Water
Important Biological Molecules • Solutions/Colloids • Acids/Bases
Monosaccharides Polysaccharides Organic Molecules — Carbohydrates
