John Dalton was one of the first to describe color blindness, which is sometimes called Daltonism.
He also discovered the Dalton's Law which describes the relationship of Partial Pressure.
And finally he proposed the existence of atoms. He only listed 6 elements but he assigned an Atomic Weight of 1.0 to Hydrogen and then proposed weights for Oxygen, Nitrogen, Carbon, Sulfur, and Phosphorus. He further postulated that chemical combination takes place between particles of different weights, which differs from the explanations provided by the Ancient Greeks.
Also, in 1803, John Dalton created the law of multiple proportions that states that when two elements can combine to form more than one compound the amounts of one of them that combines with a fixed amount of the other will exhibit a simple multiple relation.

The scientist who thought the atom was hard solid ball was?
The scientist who first proposed the idea of the atom as a hard solid ball was John Dalton in the early 19th century. Dalton's atomic theory described atoms as tiny, indivisible particles that made up all matter.
What is a positive particle with a mass of 1 Dalton?
A proton is a positive particle with a mass of approximately 1 Dalton. It is found in the nucleus of an atom and carries a positive electric charge.
Who is model of the atom has no subatomic particles?
The model of the atom with no subatomic particles is the Dalton model, proposed by John Dalton in the early 19th century. In this model, atoms were considered indivisible and the smallest building blocks of matter. Subatomic particles like protons, neutrons, and electrons were not discovered until much later.
What ideas about the atom did Democritus and John Dalton share?
Democritus and John Dalton both believed that atoms were indivisible and made up all matter. They shared the idea that atoms were small, solid particles that could not be divided further.

What did john Dalton combine with the Greek theory of the atom?
John Dalton put forward the idea that each element is made of a different sort of atom. Each kind of atom had its own properties such as an individual mass.
