About John Dalton
John Dalton was born in a poor family in 1766 in England .
He began his career as a teacher at the age of 12 .
At 7 years later he become a school principal.
In 1793 Dalton left for Manchester to teach Mathematics Physics and Chemistry in a college .
He spent most of his life their teaching and researching.
In 1808 he presented is atomic theory which was a turning point in the study of matter .
Explanation:
Dalton based his theory on two laws: the law of conservation of mass and the law of constant composition. The law of conservation of mass says that matter is not created or destroyed in a closed system. ... The law of constant composition says that a pure compound will always have the same proportion of the same elements.
