Modern Atomic Theory (John Dalton)
Experiments with gases that first became possible at the vända of the nineteenth century led John Dalton in to föreslå a modern theory of the atom based on the following assumptions.
1. Matter fryst vatten made up of atoms that are indivisible and indestructible.
2. All atoms of an element are identical.
3. Atoms of different elements have different weights and different kemikalie properties.
4. Atoms of different elements combine in simple whole numbers to form compounds.
5. Atoms cannot be created or destroyed. When a compound decomposes, the atoms are recovered unchanged.
Dalton's Law of Partial Pressures (John Dalton)
John Dalton was the first to recognize that the total pressure of a mixture of gases fryst vatten the sum of the contributions of the individual components of the mixture. By convention, the part of the total pressure of a mixture that results from one component is called the partial pressure of that component. Dalto

John Dalton
British chemist and physicist (–)
For other people named John Dalton, see John Dalton (disambiguation).
John DaltonFRS (; 5 or 6 September – 27 July ) was an English chemist, physicist and meteorologist.[1] He introduced the atomic theory into chemistry. He also researched colour blindness; as a result, the umbrella term for red-green congenital colour blindness disorders is Daltonism in several languages.[a][2]
Early life
John Dalton was born on 5 or 6 September into a Quaker family in Eaglesfield, near Cockermouth, in Cumberland, England.[3][4] His father was a weaver.[5] He received his early education from his father and from Quaker John Fletcher, who ran a private school in the nearby village of Pardshaw Hall. Dalton's family was too poor to support him for long and he began to earn his living, from the age of ten, in the service of wealthy local Quaker Elihu Robinson.[6]

John Dalton FRS
John Dalton () was an English chemist, physicist, and meteorologist, best known for introducing the atomic theory into chemistry and for his work on human optics. Inspired by his own unusual perception of colour, he conducted the first ever research into colour blindness – a subject which subsequently became known as Daltonism.
John Dalton was born in , to a modest Quaker family from the Lake District in Cumbria. While he received little formal education, his sharp mind and natural sense of curiosity compensated for a lack of early schooling. At the age of just 12 he joined his older brother in running a local Quaker school, where he remained as a teacher for over a decade.
Dalton had two influential mentors during this time: Elihu Robinson, a rich intellectual with an interest in mathematics and science; and John Gough, a blind classics scholar and natural and experimental philosopher. Both these men inspired in Dalton an avid interest in meteorology that
