There are numerous atomic theories no longer accepted by science, some of which were never accepted. One of the more popular models now rejected is the plumb puddingmodel, in which protons and electrons were clumped together in the atomic nucleus.
We now know only protons and neutrons occupy the nucleus, while electrons "orbit" in clouds known as "probability shells" associated with energy states. To drop to a lower state an electron emits a photon, a bundle of electromagnetic radiation known as light.
The planetary model, that electrons orbit atomic nuclei the way planets orbit the solar system is still taught because it is a useful model, but it is also inaccurate.

What are the two characteristics of an acceptable theory?
An "acceptable theory" is both 1. unproven in the complete sense of the word and yet- 2. yeilds the same results time after time Do not confuse this word with hypothesis or hunch when speaking science. "I have a theory that Jennifer Aniston will remarry" is not a valid sentence! You have a hunch, but not a theory.
John palton with his formulated the theory of relativity?
palton's atomic theory
What theory of matter provides the basis for your understanding of fluids?
It is the atomic theory of matter
What evidence led Dalton to propose his atomic theory?
There was no concrete evidence that led Dalton to propose his atomic theory. He proposed this theory based on logical explanations about the behavior of elements, gases or materials.
What is the definition of the atomic theory?
I'm sorry, I don't know what that means. Maybe this: Atomic theory is a theory that matter is made up of small particles called atoms
What was Dalton's major contribution to science?
Atomic Theory
Was the science affected by the Hiroshima bombing?
The modern atomic theory.
Did the ancient Greeks do scientific experiments on Democritus's atomic theory?
The ancient Greeks did not perform any experiments to test the atomic theory proposed by Democritus. To the ancient Greeks the atomic theory was a part of philosophy, not science.
Why was the atomic theory imoportant when first discovered?
because back then they need other methods of science to create more mothion and so then Democritus thought of the atomic theory.
What was lavoisiers greatest contribution to science?
His atomic theory. He was the one who thought that there were atoms in everything.
Why do you think our current of atomic structure is well accepted as a scientific theory but is not a scientific law?
In science, "theory" is the name applied to well-established scientific knowledge. It doesn't mean that there are doubts about the atomic theory.
What is a sentence with Subatomic Particles?
Although both made entirely from the element carbon, the atomic structure of diamond is different from that of graphite.

What did Dalton's atomic theory contribute to science (apex)?
It formed the basis upon which the rest of chemistry was built.
What was Aristotle's objection to the atomic theory?
Aristotle was against atomic theory considering that matter is formed from fire, air, earth and water.His conceptions delayed the development of science especially because of the harmful influence of Christianity.
What other contributions did John Dalton make to science?
color blindness
What are the contribution of Niels Bohr in the development of science and technology in atomic theory?
Neil bohr has done research in quantum mechanics.
