Life, Achievements, and contribution to our understanding of matter or atomic structure:


  • Chemist John Dalton was born September 6, 1766, in Eagles field, England.
  • He was educated in Quaker school in his village in Cumberland.
  • "Dalton's experiments on gases led to his discovery that the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the same space."
  • " In 1803 this scientific principle officially came to be known as Dalton's Law of Partial Pressures. "
  • "Dalton introduced his belief that atoms of different elements could be universally distinguished based on their varying atomic weights. In so doing, he became the first scientist to explain the behavior of atoms in terms of the measurement of weight. He also uncovered the fact that atoms couldn't be created or destroyed."
  • He was put in ground in July 27 1844.


"Interested in meteorology and atmospheric chemistry, known as father of modern atomic theory, developed four postulates describing relationship between elements and compounds."

Contributions to understanding the atom

"Elements are made of atoms. Atoms of given elements have unique characteristic; atoms combine in small, whole-number ratios to form compounds; different compounds contain atoms in different ratios. "
