John Dalton is considered as the father of chemistry because of his first model of an atom.They are as follow: 1. Every matter is made up of very small particles known as an atom which are indivisible.
2. Atoms cannot be created nor destroyed by any chemical process i.e..., atoms are indestructible. 3. All atoms of same element are same i.e.., identical in shape, mass, chemical properties etc. 4. Atoms of different elements are different sizes, masses and chemical properties etc. 5. Atoms of 2 or more elements combine together in a to form compound atoms, which they do so in simple numerical ratios(1:1 etc).
the automatic theory John Dalton's theory was all about the idea that the atoms of different elements could be well-known by differences in their weights.
Law of multiple proportions
what is john daltons scientific attitude
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.
john dalton atom is from bigger atom into smallest atom can broken it into smallest piece / part same too atom
wave theory of light
Diathesis-stress Theory
the Greek Philosophers did not test their theory.
ask jimmy lyons
The atom. Considered by Dalton to be indivisible and indestructible.
How can an STM help prove Daltons theory
John Dalton's atomic theory indicated that atoms were indivisible spheres. When JJ Thomson did his work with cathode ray tubes, he discovered that atoms contain electrons, which meant that the atom is not indivisible, that there are smaller particles within
density
A Dalton's model of atom doesn't exist. Dalton principles are not in agreement with the discovery of isotopes and nonstoichiometric compounds.

dalton wasnt the one who experimented with gold, rutherford was the one who did the gold foil experiment.
2.
In Dalton's theory the electrons in the atom travel in a one layered orbital rotation around the nucleus, in the modern, or electron cloud, theory the electrons travel in a more radical patterned movement while still staying in their respected energy levels.
