The history of the atomic theory
Atoms have been studied by many people and each person had different perspective on them they each had there own theories with truth and uncertaincy, well talk about how the atom has changed since its discovery.

In BCE 400 Democritus develops the idea that everything is made of tiny, invisible and indivisible spheres of matter of infinite type and number called atoms. Democritus's theory was later revived in 1649 when a french professor publishes a book that the universe is made up of atoms and the void.
Then came John Dalton in 1803 who took into mind the ideas of the ancient Greeks in the description of an atom. His theory states that atoms are indivisible, atoms of a given element are identical and compounds are combinations of different types of atoms. John was right for some of it since neutrons were not discovered until 1932 which didn't help for the later years or present years.
John dalton was born september 6,1766 into a quaker family of tradesmen in Eaglesfield, Cumberland, England His father Joseph was a weaver and his grandfather Jonathan was a shoemaker. His father married a woman named Deborah greenup in 1755 when they had children Dalton was the youngest from the three children. Dalton attended Jhon Fletchers Quaker grammer school and when dalton was 12 years old fletcher turned the school over to his older brother and called upon dalton to asist him with teaching and 2 years later bought a school in kendal where they teached about 60 students. As a techer dalton drew upon the experiences of two important mentors: Elihu Robinson and J hon Gough from them he learned the rudiments of Mathematics, greek, and latin. The two men were also amatuer meteorologists which made dalton retain an avid interest in meteorologic measurement for the rest of his life. In 1739 Dalton moved to Manchester to teach mathematics at a dissenting academy he took with him the proof sheets of his first book, a collection of essays on meteorologic topics based on his ownit observations together with those of his friends John Gough and Peter Crosthwaite. The work was published in 1793 it wasnt big but it had original ideas and with his more developed articles made meteorology transition from folklore to a scientic pursuit.
