Development of Atomic Theory:
Atoms, Ions, and Isotopes
Development of Atomic Theory:
1. Discoverer of the nucleus.
2. Discoverer of the neutron.
3. Developed the “Uncertainty Principle.”
4. Calculated the mass of an electron.
5. Who is credited with the Continuous Theory of Matter?
6. Law of Conservation of Mass
7. Law of Multiple Proportions
8. First mention of the atom.
9. Roger Bacon was noted for?
10. Atomic model of the atom having a uniform positive charge with enough electrons
to make the atom neutral
11. Attempted transmutation of metals.
12. Joseph Proust
13. Determined the charge of an electron.
14. Discontinuous Theory of Matter.
15. Atomic model that has electrons moving around the nucleus as waves.
16. Discovered “cathode Rays” the first evidence of electrons.
17. Atomic model described as being completely solid and homogeneous with no internal structures.
18. Discovered the proton.
19. Henry Moseley.
20. Describes the photon as a quantum of light; particles of radiation.
21. Oil Drop Experiment.
22. Atomic model describing electron’s position in orbitals.
23. Proposed that light has particle like properties.
24. Discovers the electron.
25. Which experiment used alpha particles?
26. Proposed the concept of matter waves i.e. particles (matter) can have properties of waves
27. Model of the atom having a positively charged nucleus with electrons traveling
around the nucleus.
28. Atomic model that treats electrons as particles traveling around the nucleus in
orbits having specific energy.
29. Determined that the energy of one quantum of radiation (light) is proportional to its frequency.
30. Explained the photoelectric effect.
31. Rutherford discovered the_____ with his________experiment; also discovered the________.
32. These rays were deflected away from a negatively charged plate.
33. Heated bodies emit the same color light at the same temperatures.
34. This early atomic theory is still used as the basis for modern atomic theory.
35. Spectral lines result from electrons dropping down to lower energy levels
emitting energy in the form of light.
