Document Summary

Reductionism= reducing complex systems to simpler components that are more manageable to study. C, o, h, n make up 96% of living matter. P, s, ca, k and a few others make up the other 4% Trace elements = those elements required by an organism in only minute qualities ie fe. Atomic structure determines the behavior of an element. An atom is the smallest unit of matter that still retains the properties of an element. Proton and neutron about same in mass- 1. 7 x 10^-24 g. Usually use the unit called dalton to describe atoms subatomic particles and molecules dalton is the same as the atomic mass unit or amu. Protons and neutrons have masses close to 1dalton. Mass of an electron is ,0000 of a neutron and proton > we ignore electrons when finding out the weight of an atom.
