John Dalton.Químico y físico inglés. Sus trabajos fueron de gran trascendencia para establecer un nexo concreto entre las representaciones de la filosofía natural sobre los átomos, sobre los elementos primarios, y los datos experimentales: Dalton consideraba los elementos químicos como especies de átomos que poseían una caracteríctica cuantitativa rigurosamente determinada –peso ...

Dalton's Atomic Theory was formulated by John Dalton in 1808, and it remains a fundamental tenet of chemistry to this day. The five main points are: Matter is made up of atoms, small and indivisible particles. All atoms of the same element are identical and have the same mass. Atoms of different elements vary in size, mass, and chemical behavior.
25 de jul. de 2018 · John Dalton, El daltónico que vislumbró los átomos.
