The modification of John Dalton's atomic theory is that atoms are further divisible into subatomic particles like protons, neutrons, and electrons. This modern understanding of the atom has been supported by experimental evidence, leading to the development of the nuclear model of the atom.

How the first atomic theory was formed?
john dalton develop an atomic theory in 1803, based on idea of the atomic exsiting
Whose ideas led to the atomic theory of matter?
The idea that led to the atomic theory of matter, was John Dalton.
What is Daltons Greek model?
Dalton's Greek model, proposed by John Dalton in the early 19th century, was an atomic theory that stated that all matter is composed of indivisible and indestructible particles called atoms. This theory laid the foundation for our modern understanding of the structure of matter and the development of the field of chemistry.
