The Chemical Properties of Life chapter 2 Life is made up of matter Chemistry is the study of matter and how its properties change. These changes allow the transition from one structure to the next Particulate Microscopic Macroscopic The Atomic Theory = Carbon atom Oxygen = Magnesium Carbon atom Carbon atom Oxygen CO2 The Internal Structure Atom Atom= Cathode Ray exp gave negative charges, but the atom Is neutral so.. Negative charges - - - Dense positive charge spread over the region nucleus So, the Atom is mostly Space!! The Nuclear Atom Neutron Proton Electron The Helium Atom Neutral !
