TOC:Electron Shells FoldableDrawing an Atom
Electron Shells1st level holds only 2 electrons
Electron Shells2nd level can hold only 8 electrons
1st level must be full to move on to level 2
Electron Shells3rd level hold up to 18 electrons
2nd level must be full to move to level 3
Drawing an AtomUse the periodic table to find the following information:
