Atoms Foldable
Make an eight page foldable illustrating different atoms. Each elements page will have the following items listed and illustrated.
· Protons should be colored red
· Neutrons should be colored brown
· Electrons should be colored blue
· Around the protons and neutrons should be a penciled in outline noting the nucleus of the atom.
· The name of the element should be completely written out
· Include the atoms atomic number
· Include the atomic mass
· Include the atomic symbol
· Include the number of protons
· Include the number of electrons
· Include the number of Neutrons
