2.  October 23, 1875 – March 23, 1946  American physical chemist  Married Hylda Tafler for 53 years  Had two sons  He couldn’t support his family financially so he left them Personal Story

3. Idea of the Atom  He believed that the atom was shaped of a cube and the corners represent the electrons  Discovered more and more of chemical bonds  He studied about special relativity and gained more knowledge on mathematical physics and study of space time Atomic model known as the Lewis Langmuir octet

4. Area Of Study  Study of space-time  National Academy of Sciences  Harvard University at 15  Gilbert was the first scientist to produce heavy water, experimenting with double weight hydrogen atoms  Worked with Ernest Lawrence in the invention of the cyclotron  Atom-smashing experiments.

5. Major Scientific Contribution  Gilbert Lewis is well known for the discovery of covalent bonds and purification of heavy water  Thermodynamics - working with heat and mechanical energy  He showed how to write formulas using dots to represent the electrons for example Example: O::C::O for carbon dioxide or H:Cl for hydrogen chloride.
