The Electron Dot Diagram
Valence electrons
Law of Conservation of Mass
rearranges molecules, but does not affect their internal structure
shows you that each dot represents valence electrons only
maybe considered to be the toal mass of protons, neutrons, and electrons in a single atom
Compound
Period
Groups
A physical change
