The Photoelectric effect: A phenomenon in which ultraviiolet light is shined on a metal releases electrons. http://sunenergyfacts.com/wp-content/uploads/2008/01/photoelectric_effect.gif
Alpha Particle: Used in gold-foil experiment in 1908. They are alsp another name for Helium Nuclei. http://www.ionactive.co.uk/glossaryimages/002AlphaParticle_200by200.jpg
Mendeleev: Devised first periodic table in 1869. http://www.cartage.org.lb/en/themes/sciences/chemistry/generalchemistry/elements/periodic/formulated/mendelev.gif
Neutron: discovered by Chadwick in 1932. http://lc.brooklyn.cuny.edu/smarttutor/core3_22/images/Atom_structure_neutron2.gif

1923 DeBroglie proposed that electrons can act like waves. http://www.malaspina.com/jpg/debroglie.jpg
Bohr proposed model of the atom that was half classical, and half quantum. http://www.jewoftheday.com/Ulpan/Images/NeilsBorh.jpg
The Gold-Foil experiment helped Rutherford discover the nucleus. http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter02/Text_Images/FG02_05.JPG
Heisenberg proposed the Uncertainty Principle in 1920's. http://osulibrary.oregonstate.edu/specialcollections/coll/nonspcoll/catalogue/portrait-heisenberg-600w.jpg
