FIN 3826 Chapter : Chapter 5
Document Summary
Basic chemistry: we are going to begin by using a reductionist approach. Scale of nature: what are the sizes of biologically important structures. Smallest atomic level10^-8 m largest atomic level(ecosystems) 10^6 m. A reductionist approach reduces things in the smallest parts. A wholist approach i can only study when the system is intact. No approach is better than the other you need both. You start at one end and move to the other. Whether or not something dissolves in a solution. Smallest unit of matter separable by normal chemical means. Smallest unit of an element that retains all of the elements properties. An atom is composed of many smaller particles. Proton charge of +1 have a mass of 1 dalton. Neutron charge of 0 have a mass of 1 dalton. Electron charge of -1 have approximately no mass. When looking for atomic numbers look at the protons. When looking for atomic masses add protons and neutrons.
