John Dalton

John Dalton thought that atoms were like little marbles, and also studied how elements combine to form compounds.
The physicist John Dalton is credited with comparing atoms to marbles in his atomic theory proposed in the early 19th century. Dalton's theory suggested that each element is made up of its own unique type of atom, much like how marbles of different colors and sizes represent different elements.
Dalton. Dalton's atomic theory stated that atoms are indivisible and indestructible and unchangeable.

No, Dalton did not say that all atoms are the same size. Instead, Dalton proposed that all elements are composed of indivisible particles called atoms, and that atoms of different elements have different sizes and properties.

According to John Dalton, all the atoms of a single element will have the same mass. This is the basis for the modern atomic theory.
It was not John Dalton who first suggested the idea of atoms. It was the Greek philosopher and mathematician Democritus who first suggested the existence of atoms.

John Dalton believed that all matter is composed of tiny indivisible particles called atoms, and that different elements have different types of atoms. He also proposed that atoms combine in simple whole number ratios to form compounds. Dalton's atomic theory revolutionized the study of chemistry.
Amongst other things, John Dalton thought of matter as being made up of particles. His particle theory is sometimes referred to as the 'billiard ball model' since he thought of atoms as being indivisible, unlike what we know nowadays. He also worked on the chemical formulae of different substances.
