John Dalton
John Dalton was a bright secure child. He was very smart. Infact, he was so smart in mathematics that he taught it to high school kids in a Quaker school when he was only 15 years old! John was a British chemist and physicist. His mother was Deborah Greenup of a Quaker farming family. John could of got his education was anyone. They most likely believe it was his father. John descovered a theory...... For more information on his theory, search "John Dalton's Scientific Discoveries" on google and you will find many results.
If i remember correctly, Dalton's focuses more on the nucleus while Thompson's focuses more on electrons. But I'm not sure. well in 1803 John Dalton makes a strong case that atoms are small, solid balls and Joeseph John Thompson discovers electrons, and developed plum pudding model of an atom..... Dalton says that nothings smaller than the atom, but Thompson says that electrons are.

No, he died more than 100 years before the atomic bomb was built.
John Dalton was one of the first men who theorized what the atom looks like(Dalton's Atomic Theory). And he also discovered that the pressure of 2 or more gases in one container can be known just by adding the individual pressures of each gases, we call it today as "Dalton's Rule of Partial Pressure", in honor of his brilliance!
The Law of Multiple Proportions was developed by John Dalton based on the Law of Definite Proportions, was part of what laid the groundwork for his atomic theory, and for the basis of chemical formulas for compounds.English chemist John Dalton
John Dalton in 1803.See the Web Links to the left of this answer for more information.
The theory that elements in a compound do not always combine in the same fixed ratio was proposed by John Dalton in the early 19th century. This idea laid the foundation for the development of the law of multiple proportions, which states that when elements form more than one compound, the ratios of the masses of one element that combine with a fixed mass of the other element can be expressed in small whole numbers.
John Dalton is typically not credited with creating the first atomic theory because other scientists before him, such as Democritus and Antoine Lavoisier, had proposed ideas about the atom. Dalton's theory, however, was more comprehensive and backed by experimental evidence, which led to its widespread acceptance in the scientific community.
