Solution

History of Atoms

1. NWANOIACTES

1704, Proposed a mechanical universe with small solid masses in motion.

2. HJATNNLOOD

1803, Proposed an "atomic theory" with spherical solid atoms based upon measurable properties of mass.

3. PNOHOJSMJT

1897, Studied "canal rays" and found they were associated with the proton H + .

4. LENEIEEMDDIRTMV

1869, Arranged elements into 7 groups with similar properties.

5. NETRHUORFRESRDET

1911, He also assumed that the electrons were located outside the nucleus.

6. BNLSIROHE

1922, His atomic model had atoms built up of sucessive orbital shells of electrons.

7. GORERHNSDCI

1930, Introduced "wave mechanics" as a mathematical model of the atom.

8. AISAWCHCMEJDK

1932, Discovered the neutron.
