Document Summary
4. 1 is pretty much a general chemistry recap: if you are pretty fluent in chemistry, feel free to skim it or jump ahead to 4. 2 . If you are really unfamiliar with chemistry, be sure to read the whole chapter . There can be a single, double or triple covalent bond. Ionic bonding: when atoms transfer electrons to fill their valence shell. The atom that donates the negative electron, becomes a positive ion (cation). The atom that accepts the negative electron becomes a negative ion (anion: hydrogen bonding: when atoms slightly share electrons in a very weak covalent bond, as one of the atoms hogs" the electron. Hydrogen bonds occur between molecules, not within molecules. Composition reaction: a + b ab - food molecules produced this way. Decomposition reaction: ab a + b - food molecules breaking down in processing, digestion, or by enzymatic reactions.
