- I wonder how small this can be?
- John Dalton1. Believed that all matter was made of atoms2. Believed atoms couldn't be created or destroyed3.Used data from air pressure and water vapor experiments to create his atomic theory
- J.J. Thomson1. Used cathode ray tubes2. Determined the partialsthat produces electricalcurrant3. Discoveredthat atoms have charges
- Ernest Rutherford1. Developeda way to test the plum pudding model2. Shot tiny positivelycharged particles out of a particle gun, towarda thin pieceof gold foil3. Detected reflected particles at variousangles
- Niels bohr1. Believed electrons occupy specific, or exact, energy levels2. Said energy levels are specific distances from the nucleus3. Said there are specific amounts of energy that are requiredto move electrons to the next energy level
- Erwin Schrodinger1. Modeled a wave equation that allowed scientists to identify property of electrons as both a wave and a particle 2. Believed electrons do not stay in a certain orbit but can have a predicted zone around the nucleus 3. Believed the wave equation could predict the probable (but not exact) location of an electron
